This is a preparatory patch.
efi_dp_split_file_path() is used to create device_path and file_path
from file_path for efi_setup_loaded_image().
In a special case, however, of HARDWARE_DEVICE/MEMORY, it doesn't
work expectedly since this path doesn't contain any FILE_PATH sub-type.
This patch makes a workaround.
