nvme/fio_plugin: add print_qid_mappings option 



print_qid_mappings=1 will now add logging messages
showing the {filename,qid} tuples associated with
each job.

Note that for the nvme plugin, the filename is
essentially the transport ID.  We just print that
filename for simplicity rather than reconstructing
a transport ID string from the ctrlr object.
