[SCSI] qla2xxx: Handle unaligned sector writes during NVRAM/VPD updates.
Since both NVRAM and VPD regions of the flash reside on unaligned
sector boundaries, during update, the driver must perform a
read-modify-write operation to the composite NVRAM/VPD region.
This affects ISP25xx type boards only.
