scsi: qla2xxx: Fix incorrect region-size setting in optrom SYSFS routines

commit 5cbdae10bf11f96e30b4d14de7b08c8b490e903c upstream.

Commit e6f77540c067 ("scsi: qla2xxx: Fix an integer overflow in sysfs
code") incorrectly set 'optrom_region_size' to 'start+size', which can
overflow option-rom boundaries when 'start' is non-zero.  Continue setting
optrom_region_size to the proper adjusted value of 'size'.
