Marc Kleine-Budde 91a55c72a8 can: m_can: m_can_get_berr_counter(): don't wake up controller if interface is down ...

If the interface is down, the CAN controller might be powered down, the
clock disabled, and/or it's external reset asserted.

Don't wake up the controller to read the CAN bus error counters, if the
interface is down.
