From: Vishakha Channapattan <vishakhavc@xxxxxxxxxx>
Added a log message in sata completion path to log 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, 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, log message of the following
format will be logged -
[ 1712.951735] pm80xx0:: mpi_sata_completion XXXX: Unknown status
device_id XXXXX status 0xX tag XX
