[PATCH] udp: make function udp_skb_dtor_locked static

From: Colin King
Date: Wed May 17 2017 - 04:51:24 EST

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Function udp_skb_dtor_locked does not need to be in global scope
so make it static to fix sparse warning:

net/ipv4/udp.c: warning: symbol 'udp_skb_dtor_locked' was not
declared. Should it be static?

Fixes: 6dfb4367cd911d ("udp: keep the sk_receive_queue held when splicing")
