As far as I can see the v2 patch is correct, it sends the BLOCK event when the
rfkill key was pressed to block the radio and the UNBLOCK event when the rfkill
key was pressed to unblock the radio.

The change compared to v1 was needed to prevent BLOCK events to be send
when user has manually disabled the radio for the interface through another
interface then rfkill (and thus wasn't a rfkill event).
