net: Fix unreadable error when doing poll operation on tcp socket.

Browse source 
When do poll operation and the tcp connection state is TCP_ALLOCATED, eventset(POLLERR|POLLHUP) is return, causing the libuv poll_multiple_handles to fail.

Verification: Use the libuv test case ` uv_run_tests poll_multiple_handles`.
