Btrfs: stop all workers before cleaning up roots
Dave reported a panic because the extent_root->commit_root was NULL in the
caching kthread. That is because we just unset it in free_root_pointers, which
is not the correct thing to do, we have to either wait for the caching kthread
to complete or hold the extent_commit_sem lock so we know the thread has exited.
This patch makes the kthreads all stop first and then we do our cleanup. This
should fix the race. Thanks,
