4.9-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 28ef8b49a338dc1844e86b7954cfffc7dfa2660a ]
The allocation of hwsim radio identifiers uses a post-increment from 0, so the first radio has idx 0. This idx is explicitly excluded from multicast announcements ever since, but it is unclear why.
Drop that idx check and announce the first radio as well. This makes userspace happy if it relies on these events.
