Jeff Mahoney f0382c090a btrfs: fix error handling when run_delayed_extent_op fails
commit aa7c8da35d1905d80e840d075f07d26ec90144b5 upstream.

In __btrfs_run_delayed_refs, the error path when run_delayed_extent_op
fails sets locked_ref->processing = 0 but doesn't re-increment
delayed_refs->num_heads_ready.  As a result, we end up triggering
the WARN_ON in btrfs_select_ref_head.

Fixes: d7df2c796d (Btrfs: attach delayed ref updates to delayed ref heads)
