[PATCH master] imx-usb-loader: skip initial SDP_ERROR_STATUS query for SDPS

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

We do an initial do_status() every time, which fails for i.MX8MP and
i.MX8MN:

  found i.MX8MP USB device [1fc9:0146]
  4 in err=-9, last_trans=0  00 00 00 00
  status failed

If we instead skip it for SDPS (i.e. hid_endpoint), upload works as
expected (tested on i.MX8M Nano).
