This dead lock happened on VNIF code when enabled shadow mode.
The shadow_lock path is so complex and maybe using recurisve lock
is the easiest way to avoid dead lock currently before clearing
the path or splitting the lock .

shadow_lock() and show_unlock() should just get the per-domain BIGLOCK I think. That's recursive anyway.
