netfilter: conntrack: __nf_ct_l4proto_find() always returns valid pointer
Remove unnecessary check for non-nul pointer in destroy_conntrack() given that __nf_ct_l4proto_find() returns the generic protocol tracker if the protocol is not supported. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
