net: bridge: use nla_total_size_64bit() in br_get_linkxstats_size()

BugLink: https://bugs.launchpad.net/bugs/1950014
[ Upstream commit dbe0b88064494b7bb6a9b2aa7e085b14a3112d44 ]

bridge_fill_linkxstats() is using nla_reserve_64bit().

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