HID: amd_sfh: return an error when response wait times out

amdtp_wait_for_response() waits for request_done before completing a
report request. wait_event_interruptible_timeout() returns 0 when the
wait expires, but the current code treats only negative values as errors
and returns success on timeout.

Return -ETIMEDOUT when the response wait expires while preserving the
existing success path when the response has already been observed.
