Btrfs: use the new helper wbc_to_write_flags
This updates btrfs to use the helper wbc_to_write_flags which has been
applied in ext4/xfs/f2fs/block.
Please note that, with this, btrfs's dirty pages written by a
writeback job will carry the flag REQ_BACKGROUND, which is currently
used by writeback-throttle to determine whether it should go to get a
request or wait.
