rfkill: don't restore software blocked state on persistent devices
The setting of the "persistent" flag is also made more explicit using a new rfkill_init_sw_state() function, instead of special-casing rfkill_set_sw_state() when it is called before registration. Suspend is a bit of a corner case so we try to get away without adding another hack to rfkill-input - it's going to be removed soon. If the state does change over suspend, users will simply have to prod rfkill-input twice in order to toggle the state. Userspace policy agents will be able to implement a more consistent user experience. For example, they can avoid the above problem if they toggle devices individually. Then there would be no "global state" to get out of sync. Currently there are only two rfkill drivers with persistent soft-blocked state. thinkpad-acpi already checks the software state on resume. eeepc-laptop will require modification.
