[PATCH 6/7] qemu: tpm: Remove TPM state files and directory only when undefining a VM

When share storage for the TPM state files has been setup betwen hosts then remove the TPM state files and directory only when undefining a VM and only if the attribute persistent_state is not set. Avoid removing the TPM state files and directory structure when a VM is migrated and shared storage is used since this would also remove those files and directory structure on the destination side.
