Now that we are using REQ_OP_WRITE_ZEROES for all zeroing needs in the
kernel there is very little use left for REQ_OP_WRITE_SAME. We only
have two callers left, and both just export optional protocol features
to remote systems: DRBD and the target code.
Do we have any major users of those? If not removing it will clean up
a few warts in the block layer.
