[PATCH] uml: use get_random_bytes() after random pool is seeded



When the UML network driver generates random MACs for its devices, it was
possible for a number of UMLs to get the same MACs because the ethernet
initialization was done before the random pool was properly seeded.

This patch moves the initialization later so that it gets better randomness.
