Eric Dumazet 9702e7fb63 sctp: support MSG_ERRQUEUE flag in recvmsg()
[ Upstream commit 4746b36b1a ]

For some reason sctp_poll() generates EPOLLERR if sk->sk_error_queue
is not empty but recvmsg() can not drain the error queue yet.

This is needed to better support timestamping.

I had to export inet_recv_error(), since sctp
can be compiled as a module.
