[SCSI] qla2xxx: Check alternate 'reason' code during GPSC status handling.
Some switches return 0x09 (Command not supported) as the reason code for GPSC failure. Check for this code, and disable additional GPSC queries if found. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
