When the NVMf controller's flag dif_insert_or_strip is enabled, DIF is
inserted for write I/O and stripped for read I/O, and the corresponding
NVMe-oF initiator should not be aware of the DIF setting of the
backend bdev.
Hence this patch hides the DIF setting of the backend bdev
when the flag dif_insert_or_strip is enabled.

But NVMf controller knows if DIF/insert/strip is enabled now by the
