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

[ Upstream commit 0854a051 ]

Commit de179966 ("net: bridge: add STP xstats")
added an additional nla_reserve_64bit() in br_fill_linkxstats(),
but forgot to update br_get_linkxstats_size() accordingly.

This can trigger the following in rtnl_stats_get()

	WARN_ON(err == -EMSGSIZE);

Fixes: de179966 ("net: bridge: add STP xstats")
