HID: logitech-hidpp: Remove wtp_get_config() call from probe()

For WTP devices which start disconnected (paired with the unifying
receiver, but not connected atm) hidpp_connect_event() takes care
of calling wtp_get_config() when the device later connects.

There is no need to have a separate code path for WTP devices which
are connected at probe() time, these can use the same code-path since
probe() will queue hidpp_connect_event() for those at probe time.

Drop the unnecessary wtp_get_config() call from probe().

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)
