efi_loader: use TPL_NOTIFY for network timer event
We use a timer to poll the network.
iPXE is used for booting from iSCSI drives. It has been changed to run at
TPL_CALLBACK most of the time (which is not what the UEFI spec
recommends).
By changing our timer to TPL_NOTIFY we can ensure that it is nevertheless
executed.
