MLK-16532 usb: chipidea: do not call WARN_ON if controller is going to suspend twice

At current PM framework, the dev->runtime_suspend may be called after
dev->system_suspend is called, and the dev->runtime_resume may be called
before dev->system_suspend is called. So, we need to delete WARN_ON to
avoid before dump:
