drbd: Store op in drbd_peer_request

(Sort of) cherry-picked from the out-of-tree drbd9 branch. Original
commit message by Joel Colledge:

    This simplifies drbd_submit_peer_request by removing most of the
    arguments. It also makes the treatment of the op better aligned with
    that in struct bio.

    Determine fault_type dynamically using information which is already
    available instead of passing it in as a parameter.

Note: The opf in receive_rs_deallocated was changed from
REQ_OP_WRITE_ZEROES to REQ_OP_DISCARD. This was required in the
out-of-tree module, and does not matter in-tree. The opf is ignored
anyway in drbd_submit_peer_request, since the discard/zero-out is
decided by the EE_TRIM flag.
