[SCSI] qla2xxx: Update FCP priority information to firmware before se…

…nding IOs

The FCP priority info was not being updated properly in certain situations.
Here are the changes that needs to be done to take care of this issue:
1. No need to check fcport->state for FCS_UNCONFIGURED in
qla24xx_update_fcport_fcp_prio(), since an invalid loop id check is
already performed which is sufficient.
2. Add the missing qla24xx_update_fcport_fcp_prio() function call
within qla2x00_update_fcport() function, so that the priority info
is updated on every port addition or change.
3. Perform proper adapter types checking.
4. Other changes, associated with DEBUG/printk's and parameter passing.
