[U-Boot] [PATCH] net: eth-uclass: call stop only for active devices

[Keerthy]

Currently stop is being called unconditionally without even
checking if start is called. In case of multiple instances eth
being present many devices might just be initialized without
a start call in such cases stop might lead unpredictable behaviors
including aborts and crashes. Hence add a check before calling stop.
