HID: logitech-hidpp: simplify printing of HID++ version

Browse Source 
Simply always print the HID++ version on hidpp_root_get_protocol_version
success.

This also fixes the version not being printed when a HID++ device
connected through a receiver is already connected when the hidpp driver
is loaded.
