Ricardo Ribalda 16045708a3 media: uvcvideo: Recover stalled ElGato devices 
Elgato Cam Link 4k can be in a stalled state if the resolution of
the external source has changed while the firmware initializes.
Once in this state, the device is useless until it receives a
USB reset. It has even been observed that the stalled state will
continue even after unplugging the device.
