This patch allows WirelessDeviceStatus (0x1d4b) events to be detected as
connection events in the hid-logitech-hidpp module.
Devices with HIDPP_QUIRK_WIRELESS_DEVICE_STATUS use WirelessDeviceStatus
instead of traditional connect events. Since all Bluetooth LE devices seem
to act this way, HIDPP_QUIRK_CLASS_BLUETOOTH_LE aliases this quirk.
