xt_qtaguid: use sock_gen_put() instead of xt_socket_put_sk()

Browse source 
Removing obsolete xt_socket_put_sk() and using sock_gen_put() instead.
xt_socket_put_sk() was reintroduced for xt_qtaguid in one of the patches,
but it turned out sock_gen_put() supersedes xt_socket_put_sk(). So we
don't need xt_socket_put_sk() any more.

This patch is based on commit 1a8bf6eeef (netfilter: xt_socket: use sock_gen_put())
