btrfs: fix btrfs_submit_compressed_write cgroup attribution
This restores the logic from commit 46bcff2bfc5e ("btrfs: fix compressed
write bio blkcg attribution") which added cgroup attribution to btrfs
writeback. It also adds back the REQ_CGROUP_PUNT flag for these ios.
Fixes: 91507240482e ("btrfs: determine stripe boundary at bio allocation time in btrfs_submit_compressed_write")
