e1000e: i219 fix unit hang on reset and runtime D3 Unit hang may occur if multiple descriptors are available in the rings during reset or runtime suspend. This state can be detected by testing bit 8 in the FEXTNVM7 register. If this bit is set and there are pending descriptors in one of the rings, we must flush them prior to reset. Same applies entering runtime suspend.
