scsi: qla2xxx: Further limit FLASH region write access from SysFS

Recent ISPs have larger and more complex flash-write semantics
(secure-access and signing). The BSG interfaces support these semantics for
all ISPs and is exclusively used by QLogic user-space tools. Limit
flash-write operations to ISPs <= 25xx.
