e1000e: restore flow control settings properly
After a cable unplug the forced flow control settings were lost accidentally and the flow control settings fell back to the default EEPROM determined values. This breaks for people who want to run without fc enabled - after a cable reset the driver would refuse to run with fc disabled.
