Subject: [PATCH net 1/2] net: bridge: use nla_total_size_64bit() in br_get_linkxstats_size()

From: Eric Dumazet <edumazet@...gle.com>

bridge_fill_linkxstats() is using nla_reserve_64bit().

We must use nla_total_size_64bit() instead of nla_total_size()
for corresponding data structure.

Fixes: 1080ab95e3c7 ("net: bridge: add support for IGMP/MLD stats and export them via netlink")
