HID: fix USB HID devices after STD with autosuspend
This patch fixes a bug caused by reset_resume not changing the internal status flags for a device that is resumed via reset_resume. To do so the reset handlers, which correctly assume that a device is awake, can no longer do all the work of reset_resume handling.
