Eric Dumazet 72fb96e7bd l2tp: do not use udp_ioctl()
udp_ioctl(), as its name suggests, is used by UDP protocols,
but is also used by L2TP :(

L2TP should use its own handler, because it really does not
look the same.

SIOCINQ for instance should not assume UDP checksum or headers.

Thanks to Andrey and syzkaller team for providing the report
and a nice reproducer.

While crashes only happen on recent kernels (after commit
7c13f97ffd ("udp: do fwd memory scheduling on dequeue")), this
probably needs to be backported to older kernels.

Fixes: 7c13f97ffd ("udp: do fwd memory scheduling on dequeue")
Fixes: 8558467201 ("udp: Fix udp_poll() and ioctl()")
