The device tree may passed by the firmware as UEFI configuration
table. Let lsefisystab display a short text and not only the GUID
for the device tree.
Here is an example output:
grub> lsefisystab

Signature: 5453595320494249 revision: 00020046

The UEFI specification allows LoadImage() to be called with a memory
location only and without a device path. In this case FilePath will not be
set in the EFI_LOADED_IMAGE_PROTOCOL.
So in function grub_efi_get_filename() the device path argument may be
NULL. As we cannot determine the device path in this case just return NULL
from the function.

We should not try to copy any memory area which is outside of the original
fdt. If this extra memory is controlled by a hypervisor this might end
with a crash.
