btrfs: move kthread_associate_blkcg out of btrfs_submit_compressed_write
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.
