#1348793 — [PATCH 4/4] md: dm-crypt: Initialize the sector number for one request

If the crypto engine can support the bulk mode, that means the contiguous
requests from one block can be merged into one request to be handled by
crypto engine. If so, the crypto engine need the sector number of one request
to do merging action.
