[SCSI] qla4xxx: fix compile warning due to invalid extHwConfig

If the nvram is invalid qla4xxx tries to set Asuint32_t
based on the card type. If the card type is not listed
then Asuint32_t is going to be gargabe. This just fixes
that if/elseif by adding a else to catch the case for
new hardware that might not be listed yet.
