Validate the given MAC address directly in dev_set_mac_address()

Changed .ndo_validate_addr to take a second parameter containing
a sockaddr struct to be checked instead of the net_device dev_addr.
The behaviour of .ndo_validate_addr is now: if the second parameter
is NULL the net_device->dev_addr gets validate, if != NULL
the given parameter/sockaddr gets validated instead.

This patch series include adaptations for some drivers which
use .ndo_set_mac_address functions directly - to prevent double
checks and to enable validations via .ndo_validate_addr.

You have to do this as a single patch.  The kernel and drivers should
still build at each stage.
