[SCSI] mpt2sas: Tie a log info message to a specific PHY.
Add support to display additional debug info for SCSI_IO and
RAID_SCSI_IO_PASSTHROUGH sent from the normal entry queued entry
point, as well as internal generated commands, and IOCTLS. The
additional debug info included the phy number, as well as the
sas address, enclosure logical id, and slot number. This debug info
has to be enabled thru the logging_level command line option, by
default this will not be displayed.
