btrfs_submit_compressed_write should not have to care if it is called from a helper thread or not. Move the kthread_associate_blkcg handling into submit_one_async_extent, as that is the one caller that needs it. Also move the assignment of REQ_CGROUP_PUNT into cow_file_range_async, as that is the routine that sets up the helper thread offload. Signed-off-by:
