Removal of the sock_hold got lost when backporting commit 4d05239203fa
("netfilter: nf_queue: fix possible use-after-free") to 4.14
This was causing a socket leak and was caught by kmemleak.
Tested by running kmemleak again with this fix.
Fixes: ef97921ccdc2 ("netfilter: nf_queue: fix possible use-after-free") in 4.14
