HID: logitech-hidpp: Move get_wireless_feature_index() check to hidpp_connect_event()
Calling get_wireless_feature_index() from probe() causes
the wireless_feature_index to only get set for unifying devices which
are already connected at probe() time. It does not get set for devices
which connect later.
Fix this by moving get_wireless_feature_index() to hidpp_connect_event(),
this does not make a difference for devices connected at probe() since
probe() will queue the hidpp_connect_event() for those at probe time.
This series has been tested on the following devices:
Logitech Bluetooth Laser Travel Mouse (bluetooth, HID++ 1.0)
Logitech M720 Triathlon (bluetooth, HID++ 4.5)
Logitech M720 Triathlon (unifying, HID++ 4.5)
Logitech K400 Pro (unifying, HID++ 4.1)
Logitech K270 (eQUAD nano Lite, HID++ 2.0)
Logitech M185 (eQUAD nano Lite, HID++ 4.5)
Logitech LX501 keyboard (27 Mhz, HID++ builtin scroll-wheel, HID++ 1.0)
Logitech M-RAZ105 mouse (27 Mhz, HID++ extra mouse buttons, HID++ 1.0)
And by bentiss:
Logitech Touchpad T650 (unifying)
Logitech Touchpad T651 (bluetooth)
Logitech MX Master 3B (BLE)
Logitech G403 (plain USB / Gaming receiver)
