bcache: update bio->bi_opf bypass/writeback REQ_ flag hints
Flag for bypass if the IO is for read-ahead or background, unless the
read-ahead request is for metadata (eg, from gfs2).
Bypass if:
bio->bi_opf & (REQ_RAHEAD|REQ_BACKGROUND) &&
!(bio->bi_opf & REQ_META))
Writeback if:
op_is_sync(bio->bi_opf) ||
bio->bi_opf & (REQ_META|REQ_PRIO)
