nvethernet:set phy oldlink status correctly

Browse Source 
Issue: on resume the mac set speed is not called due
to which the data transmissions are not happening in
alternate suspend resume cycles.

This is because the oldlink status is not set to 1 during
the successful resume, in set_speed_work_func retries

Fix: set oldlink to 1 once setspeed is successful in
function set_speed_work_func, so that next time
ether_adjust_link will call the set speed after resume
