selinux: fix random read in selinux_ip_postroute_compat()
In commit e446f9dfe17b ("net: synack packets can be attached to request
sockets"), I missed one remaining case of invalid skb->sk->sk_security
access.
Dmitry Vyukov got a KASan report pointing to it.
Add selinux_skb_sk() helper that is responsible to get back to the
listener if skb is attached to a request socket, instead of
duplicating the logic.
Fixes: ca6fb0651883 ("tcp: attach SYNACK messages to request sockets instead of listener")
