Subject: net: use inet6_rcv_saddr to compare sockets
Patch-mainline: v4.14-rc2
Git-commit: 7a56673b58f2414679e926bba80309a037a4fd35
References: bsc#1076830
In ipv6_rcv_saddr_equal() we need to use inet6_rcv_saddr(sk) for the
ipv6 compare with the fast socket information to make sure we're doing
the proper comparisons.
Fixes: 637bc8bbe6c0 ("inet: reset tb->fastreuseport when adding a reuseport sk")
