acer-wmi: does not set persistence state by rfkill_init_sw_state
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.
