btrfs: use btrfs_fs_closing for background bg work

Browse Source 
For both unused bg deletion and async balance work we'll happily run if
the fs is closing.  However I want to move these to their own worker
thread, and they can be long running jobs, so add a check to see if
we're closing and simply bail.
