e1000e: Move pm_qos_req to e1000e adapter
e1000e is the only driver requiring pm_qos_req, instead of causing every device to waste up to 240 bytes. Allocate it for the specific driver. Signed-off-by: Thomas Graf <tgraf@suug.ch> Acked-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
