Export PollResult

[lrh2000]

#991 adds PollResult and PollIngressSingleResult. However, these two types are not accessible because they are in a private mod interface:

smoltcp/src/iface/mod.rs

Line 8 in 9cc0657

mod interface;

This needs to be fixed, otherwise no one can check the result returned by poll or poll_ingress_single:

smoltcp/src/iface/interface/mod.rs

Lines 431 to 436 in 9cc0657

	pub fn poll(
	&mut self,
	timestamp: Instant,
	device: &mut (impl Device + ?Sized),
	sockets: &mut SocketSet<'_>,
	) -> PollResult {
