efi_loader: stop network in EXIT_BOOT_SERVICES

It has been reported that memory corruption can occurred because network
packages where received after EXIT_BOOT_SERVICES. See the thread
starting at [1].

We try to remove all drivers when EXIT_BOOT_SERVICES is called. But

* Some network drivers don't call their own stop method when removed.
* Some network drivers don't have a remove method.
* Some devices have CONFIG_DM_DEVICE_REMOVE=n.

Let's call eth_halt() in EXIT_BOOT_SERVICES explicitly.
