Subject: [PATCH 4.18 017/150] netfilter: conntrack: get rid of double sizeof

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 346fa83d10934cf206e2fd0f514bf8ce186f08fe ]

sizeof(sizeof()) is quite strange and does not seem to be what
is wanted here.

The issue is detected with the help of Coccinelle.
