block: do not use REQ_FLUSH for tracking flush support The last patch added a REQ_OP_FLUSH for request_fn drivers and the next patch renames REQ_FLUSH to REQ_PREFLUSH which will be used by file systems and make_request_fn drivers so they can send a write/flush combo. This patch drops xen's use of REQ_FLUSH to track if it supports REQ_OP_FLUSH requests, so REQ_FLUSH can be deleted.
