That assertion seems to be bogus. It checks a field in an mbuf
that was just allocated in ieee80211_getmgtframe using m_getcl
and that may contain random data in the ctx pointer.

Another similar assertion in the same file is #ifdef __FreeBSD__.

Looking at the current FreeBSD code, it still abuses the rcvif
pointer for local data. But there are no such assertions, which
would be bogus in FreeBSD either.
