extmod/modlwip: Fix bug when polling listening socket with backlog=1.
The bug polling for readability was: if alloc==0 and tcp.item==NULL then
the code would incorrectly check tcp.array[iget] which is an invalid
dereference when alloc==0. This patch refactors the code to use a helper
function lwip_socket_incoming_array() to return the correct pointer for the
incomming connection array.
Fixes issue #4511.
