gfs2: Initialize bio->bi_opf early

Browse source

[ Upstream commit 4a94f052e0 ]

Pass the right blk_opf_t value to bio_alloc() so that ->bi_ops is
initialized correctly and doesn't have to be changed later.  Adjust the
call chain to pass that value through to where it is needed (and only
there).

Add a separate blk_opf_t argument to gfs2_chain_bio() instead of copying
the value from the previous bio.
