[PATCH] sky2: set mac address fix

Using the sky2 driver with bonding can result in oopses related to
reinitializing the PHY when the MAC address is changed (which bonding
is wont to do).  This patch changes sky2_set_mac_address to take less
drastic measures.

This is analagous to the skge patch here:

which fixed the issue here:
