net: add skb_to_full_sk() helper and use it in selinux_netlbl_skbuff_setsid()

Browse Source 
Generalize selinux_skb_sk() added in commit 212cd08953
("selinux: fix random read in selinux_ip_postroute_compat()")
so that we can use it other contexts.

Use it right away in selinux_netlbl_skbuff_setsid()

Fixes: ca6fb06518 ("tcp: attach SYNACK messages to request sockets instead of listener")
