nvme: Add nvm-id-ns-lba-format(CNS 0Ah) command from TP4095

I/O Command Set specific Identify Namespace data structure
for the specified LBA Format index for the NVM Command Set
specified in the CSI field.

None capabilities from nvme_id_ns structure are returned as 0 with this command
Set maximum nlbaf when identify ns for all ns is failed to print elbafs

+The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
+.sp
+On success, the structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout\&.

+============================
+
+NAME
+----
+nvme-nvm-id-ns-lba-format - Send NVMe Identify NVM Command Set specific
+Namespace data structure for specified LBA format, display structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme nvm-id-ns-lba-format' <device> [--uuid-index=<uuid-index> | -U <uuid_index>]
+                       [--lba-format-index=<lba_format_index> | -i <lba_format_index>]
+                       [-v | --verbose]
+                       [--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+Identify NVM Command Set specific Namespace data structure for the specified
+LBA format index for the NVM Command Set specified in the CSI field.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the structure may be returned in one of several ways depending
+on the option flags; the structure may be parsed by the program or the
+raw buffer may be printed to stdout.
+
+OPTIONS
+-------
+-U <uuid-index>::
+--uuid-index=<uuid-index>::
+       UUID Index of the feature
+
+-i <lba_format_index>::
+--lba-format-index=<lba_format_index>::
+       This field specifies the index into the LBA Format list identifying
+       the LBA Format capabilities that are to be returned
+
+-v::
+--verbose::
+       Increase the information detail in the output.
+
+-o <format>::
+--output-format=<format>::
+              Set the reporting format to 'normal', 'json', or
+              'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:
++
+------------
+# nvme nvm-id-ns-lba-format /dev/nvme0n1 -i 0
+------------
++
+* Have the program return the raw structure in binary:
++
+------------
+# nvme nvm-id-ns-lba-format /dev/nvme0 -i 0 -o binary > nvm_id_ns.raw
+# nvme nvm-id-ns-lba-format /dev/nvme0n1 -i 0 --output-format=binary > nvm_id_ns.raw
