[SCSI] qla2xxx: Check for a match before attempting to set FCP-priority information.
Modifying qla24xx_get_fcp_prio() to return a 'found' status
allows the driver to short circuit the 'set FCP-priority' call
and reduce the amount of noise generated in the messages file:
scsi(5): Unable to activate fcp priority, ret=0x102
scsi(5): Unable to activate fcp priority, ret=0x102
Also make qla24xx_get_fcp_prio() static.
