commit 8215af019040ce9182728afee9642d8fdeb17f59 upstream.
Acer BIOS keeps devices state when system reboot, but reset to default
device states (Wlan on, Bluetooth off, wwan on) if system cold boot.
That means BIOS's initial state is not always real persistence.
So, removed rfkill_init_sw_state because it sets initial state to
persistence then replicate to other new killswitch when rfkill-input
enabled.
After removed it, acer-wmi set initial soft-block state after rfkill
register, and doesn't allow set_block until rfkill initial finished.
