Disable SW switch regardless of HW switch state (we can only enable
radio when both SW and HW rfkill switches are off). Report to rfkill
subsystem SW switch state before HW switch state to move rfkill subsystem
to SOFT_BLOCK rather than HARD_BLOCK, otherwise in some conditions we
would not be able to turn radio back on.
