fabrics: add option to override drivers queue depth also for connect-all command

Currently it is not possible to override the fabrics drivers default
queue depth with the nvme userspace utility's 'connect-all' command,
but only when using the 'connect' command.

Add an option to override the drivers default queue depth for NVMe
over fabrics with the 'connect-all' command as we did previouslt with the
'connect' command.
