Linux 5.12.0 gives rfkill: "Cannot get wiphy information"

The wifi does work despite the warning, it has become very slow with connecting. Based on cfg80211: change netdev registration/unregistration semantics I came up with the following patch, which for me at least resolves the issue. Though I'm not sure both netdev register changes are necessary wl.diff.txt

@koosvriezen thanks for reporting! The patch looks reasonable ✅
