usb: dwc3: gadget: skip Set/Clear Halt when invalid

commit ffb80fc672c3a7b6afd0cefcb1524fb99917b2f3 upstream.

At least macOS seems to be sending
ClearFeature(ENDPOINT_HALT) to endpoints which
aren't Halted. This makes DWC3's CLEARSTALL command
time out which causes several issues for the driver.

Instead, let's just return 0 and bail out early.
