If it is something coming from mac80211, then you do not want
to send a SOFT_BLOCKED event since that will cause all other radios
to be switched off simply because the b43 interface has not been
enabled.

Off course when it represents the key state in the hardware then the
code would be fine...

The state comes from mac80211 and is set in the config() callback.

What state should be sent at the point when the hardware block is
removed? It seems to me that forcing an UNBLOCKED state gives the
wrong result. Perhaps RFKILL does need to have 4 states so that an
RFKILL_STATE_HW_UNBLOCKED state can be transmitted.
