drivers/intel/i210: Request Bus Master in .final ops
Commit bd31642ad8 (intel/i210: Set bus master bit in command register)
is only necessary because a buggy OS expects Bus Master to be set, not
because the hardware requires Bus Master during initialization. It is
thus safe to defer the Bus Master request into the .final callback.
