ppp: annotate lockless queue empty check

ppp_poll() checks whether pf->rq contains a packet without holding the
queue lock. skb_peek() requires appropriate locking or a private queue,
neither of which applies because ppp_input() can enqueue concurrently.

Only queue emptiness is needed, so use skb_queue_empty_lockless()
instead.
