José Expósito aa320fdbbb HID: hid-uclogic-params: Invalid parameter check in uclogic_params_frame_init_v1_buttonpad ...

The function performs a check on the hdev input parameters, however, it
is used before the check.

Initialize the udev variable after the sanity check to avoid a
possible NULL pointer dereference.
