usb/hcd: Send a uevent signaling that the host controller had died
This change will send an OFFLINE event to udev with the ERROR=DEAD
environment variable set when the HC dies.
By notifying user space the appropriate policies can be applied.
i.e.,
* Collect error logs.
* Notify the user that USB is no longer functional.
* Perform a graceful reboot.
