[SCSI] qla2xxx: Fallback to 'golden-firmware' operation on supported ISPs.

Browse source 
In case the onboard firmware is unable to be read or loaded for
operation, attempt to fallback to a limited-operational firmware
image stored in a different flash region.  This will allow a user
to reflash and correct a board with proper operational firmware.
