But why drop the frame? I'm still thinking that it just doesn't really
make sense to apply the rate mask to scanning at all?

The most common use case for this is probably P2P-style things where you
just don't want to use CCK, but for scanning we have
NL80211_ATTR_TX_NO_CCK_RATE for this, so there's really no need to apply
the rate mask?
