HID: hid-thrustmaster: Fix warning in thrustmaster_probe by adding endpoint check

syzbot has found a type mismatch between a USB pipe and the transfer
endpoint, which is triggered by the hid-thrustmaster driver[1].
There is a number of similar, already fixed issues [2].
In this case as in others, implementing check for endpoint type fixes the issue.
