scsi: pm80xx: Log SATA IOMB completion status on failure
Added a log message in SATA completion path to capture the status of failed
command. If the status does not match any expected status, another message
will be logged.
On IO failure with known status, the log message will be:
[ 1712.951735] pm80xx0:: mpi_sata_completion 2269: IO failed device_id 16385 status 0x1 tag XX
If the firmware returns unexpected status, a message of the following
format will be logged:
[ 1712.951735] pm80xx0:: mpi_sata_completion XXXX: Unknown status device_id XXXXX status 0xX tag XX
