Implementation details for bio based block drivers

+For bio based drivers the REQ_PREFLUSH and REQ_FUA bit are simply passed on to
+the driver if the driver sets the BLK_FEAT_WRITE_CACHE flag and the driver
needs to handle them.
*NOTE*: The REQ_FUA bit also gets passed on when the BLK_FEAT_FUA flags is
with a payload are automatically turned into a sequence of a REQ_OP_FLUSH
request followed by the actual write by the block layer.

+When the BLK_FEAT_FUA flags is set, the REQ_FUA bit is simply passed on for the
REQ_OP_WRITE request, else a REQ_OP_FLUSH request is sent by the block layer
after the completion of the write request for bio submissions with the REQ_FUA
bit set.
