b44: always set duplex mode why phy changes
Without this patch b44_check_phy() was called when the phy called the adjust callback. This method only change the mac duplex mode when the carrier was off. When the phy changed the duplex mode after the carrier was on the mac was not changed. This happened when an external phy was used.
