efi_loader: fix use after free in efi_exit() with tcg2

The efi_exit() function frees the loaded image memory by calling
efi_delete_image(). However, when CONFIG_EFI_TCG2_PROTOCOL is enabled, the
image_obj->image_type structure member is accessed after the memory has
been freed.

Fix this by performing the tcg2 measurement before the image deletion.
