[PATCH 5.16 097/227] netfilter: xt_socket: fix a typo in socket_mt_destroy()

From: Eric Dumazet <edumazet@google.com>

commit 75063c9294fb239bbe64eb72141b6871fe526d29 upstream.

Calling nf_defrag_ipv4_disable() instead of nf_defrag_ipv6_disable()
was probably not the intent.

I found this by code inspection, while chasing a possible issue in TPROXY.

Fixes: de8c12110a13 ("netfilter: disable defrag once its no longer needed")
