netfilter: xt_socket: fix a typo in socket_mt_destroy()

Origin: https://git.kernel.org/linus/75063c9294fb239bbe64eb72141b6871fe526d29

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")
