b44: fix force mac address before ifconfig up
Initializing the b44 MAC & PCI functional blocks in the controller must occur inside init_one(). This will allow access to the MAC registers. The controller was being powered up in b44_open() which would not allow access to the registers before ifconfig was up. Philip Kohlbecher found this bug.
