Btrfs: fix lock leak when resuming snapshot deletion
commit fec386ac1428f9c0e672df952cbca5cebd4e4e2f upstream.
We aren't setting path->locks[level] when we resume a snapshot deletion which
means we won't unlock the buffer when we free the path. This causes deadlocks
if we happen to re-allocate the block before we've evicted the extent buffer
from cache. Thanks,
