netfilter: nfnetlink_queue: return error number to caller

instead of returning -1 on error, return an error number to allow the
caller to handle some errors differently.

ECANCELED is used to indicate that the hook is going away and should be
ignored.

A followup patch will introduce more 'ignore this hook' conditions,
(depending on queue settings) and will move kfree_skb responsibility
to the caller.
