From: Quinn Tran <qutran@xxxxxxxxxxx>
For new adapter with multiple flash regions to write to, current code
allows FW & Boot regions to be written, while other regions are blocked
via sysfs. The fix is to block all flash read/write through sysfs
interface.
Fixes: e81d1bcbde06 ("scsi: qla2xxx: Further limit FLASH region write access from SysFS")
