Lawrence Brakmo 2585cd62f0 bpf: Only reply field should be writeable 
Currently, a sock_ops BPF program can write the op field and all the
reply fields (reply and replylong). This is a bug. The op field should
not have been writeable and there is currently no way to use replylong
field for indices >= 1. This patch enforces that only the reply field
(which equals replylong[0]) is writeable.

Fixes: 40304b2a15 ("bpf: BPF support for sock_ops")
