USB: hub: handle claim of enabled remote wakeup after reset
commit 07e72b95f5038cc82304b9a4a2eb7f9fc391ea68 upstream. Some touchscreens have buggy firmware which claims remote wakeup to be enabled after a reset. They nevertheless crash if the feature is cleared by the host. Add a check for reset resume before checking for an enabled remote wakeup feature. On compliant devices the feature must be cleared after a reset anyway.
