net: bridge: prevent too big nested attributes in br_fill_linkxstats()
After commit ff205bf8c554 ("netlink: add one debug check in nla_nest_end()")
syzbot found that br_fill_linkxstats() can send corrupted netlink packets.
Make sure the nested attribute size is bounded.
Fixes: a60c090361ea ("bridge: netlink: export per-vlan stats")
