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.
