tg3: Preserve LAA when device control is released 

This patch moves the __tg3_set_mac_addr() function earlier in the file
listing, to avoid a function prototype, and calls the function to
restore the LAA after a driver unload chip reset.  With this code in
place, the administrator can wake the machine using the LAA.
