md/raid1: fix data lost for writemostly rdev
If writemostly is enabled, alloc_behind_master_bio() will allocate a new
bio for rdev, with bi_opf set to 0. Later, raid1_write_request() will
clone from this bio, hence bi_opf is still 0 for the cloned bio. Submit
this cloned bio will end up to be read, causing write data lost.
Fix this problem by inheriting bi_opf from original bio for
behind_mast_bio.
