udp: Fix udp_poll() and ioctl()
[ Upstream commit 85584672012ee0c3b7b8e033a1ecf7c11878e45f ]
udp_poll() can in some circumstances drop frames with incorrect checksums.
Problem is we now have to lock the socket while dropping frames, or risk
sk_forward corruption.
This bug is present since commit 95766fff6b9a78d1
([UDP]: Add memory accounting.)
While we are at it, we can correct ioctl(SIOCINQ) to also drop bad frames.
