json: fix seg. fault converting NULL to JSON string

The function json_object_new_string() seg. faults when passed a
NULL pointer. This can happen, for example, when parameters retuned
by a controller (e.g. Firmware, Model Number, Serial Number, etc.)
are undefined and therefore NULL. This will cause the following
command to crash:

nvme list -v -o json
