[PATCH 3/3] cxlflash: Update debug prints in reset handlers

[Matthew R. Ochs]

The device and host reset handler contain debug prints to help
identify the entities being reset. Today these reset handlers
are based on a SCSI EH design that uses a SCSI command reference
as a means of identifying the target entity. As such, the debug
trace includes the SCSI command pointer and associated CDB. This
is not necessary as the SCSI command is simply the messenger in
these scenarios.

Refactor the debug prints in the host and reset handlers to only
present information that is applicable given the function scope.
