[PATCH] drivers/net: remove superfluous memset

	This patch covers something like this:

dev = alloc_*dev(...
...
priv = netdev_priv(dev);
memset(priv, 0, sizeof(*priv));

The memset() here is superfluous. alloc_netdev() uses kzalloc()
to allocate needed memory so there is no need to zero the priv region
twice.
