Joel Cunningham 0882e0ba89 sockets: poll clean ups ...

This makes the following poll cleanups:

 1) Add LWIP_ERROR in lwip_poll to check for invalid fds/nfds combinations.
    This fixes a possible a NULL fds dereference in lwip_poll_scan()
 2) Use has_ copies of the socket events in lwip_poll_should_wake() rather
    passing the sock pointer and accessing socket after leaving the critical
    section
