5.4-stable review patch. If anyone has any objections, please let me know.

commit dc89548c6926d68dfdda11bebc1a5258bc41d887 upstream.
The code did not check the return value of usbnet_get_endpoints. Add checks and return the error if it fails to transfer the error.
Found via static anlaysis and this is similar to commit 07161b2416f7 ("sr9800: Add check for usbnet_get_endpoints").
