Alan Somers a92fe02768 Don't retry SAS commands in response to protocol errors
sys/dev/mpr/mpr_sas_lsi.c
sys/dev/mps/mps_sas_lsi.c
	When mp[rs]sas_get_sata_identify returns
	MPI2_IOCSTATUS_SCSI_PROTOCOL_ERROR, don't bother retrying. Protocol
	errors aren't likely to be fixed by sleeping.

	Without this change, a system that generated may protocol errors due
	to signal integrity issues was taking more than an hour to boot, due
	to all the retries.
