[media] em28xx: don't sleep on disconnect
The DVB framework will try to power-down an adapter that no-one is using any more, but this assumes that the adapter is still connected to the machine. That's not always true for a USB adapter, so disable the sleep operations when the adapter has been physically unplugged. This prevents I2C write failures with error -19 from appearing occasionally in the dmesg log.
