My previous patch (several months ago) missed one instance of
changing usblp status data from local stack to alloc-ed memory.

Not having heard any complaints about this patch, I'm submitting it.  It
fixes a problem with the root hub status URB implementation; the timer
that controls the root hub polling was not getting reset during a PM
suspend.

already being unhashed on entry.

as we delete the entry, we can only poison the back pointer, not the
traversal pointer (rcu traversal only ever walks forward).

Make __d_drop() take this into account.
