scsi: qla1280: make qla1280_firmware_mutex and qla1280_fw_tbl static

Fix the following sparse warning:

drivers/scsi/qla1280.c:529:1: warning: symbol 'qla1280_firmware_mutex'
was not declared. Should it be static?
drivers/scsi/qla1280.c:538:15: warning: symbol 'qla1280_fw_tbl' was not
declared. Should it be static?
