rfkill: honour EPO state when resuming a rfkill controller

rfkill_resume() would always restore the rfkill controller state to its pre-suspend state. Now that we know when we are under EPO, kick the rfkill controller to SOFT_BLOCKED state instead of to its pre-suspend state when it is resumed while EPO mode is active.
