Subject: [PATCH] rtnetlink: fix missing size for IFLA_IF_NETNSID

From: Colin Ian King <colin.king@...onical.com>

The size for IFLA_IF_NETNSID is missing from the size calculation
because the proceeding semicolon was not removed. Fix this by removing
the semicolon.

Detected by CoverityScan, CID#1461135 ("Structurally dead code")

Fixes: 79e1ad148c84 ("rtnetlink: use netnsid to query interface")
