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.
