[libvirt] [PATCH] security: Do not restore labels on device tree binary

A device tree binary file specified by /domain/os/dtb element is a read-only resource similar to kernel and initrd files. We shouldn't restore its label when destroying a domain to avoid breaking other domains configure with the same device tree.
