[PATCH v2 2/2] qemu: tpm: Remove TPM state after successful migration

[Stefan Berger <stefanb@xxxxxxxxxxxxx>]

This patch 'fixes' the behavior of the persistent_state TPM domain XML
attribute that intends to preserve the state of the TPM but should not
keep the state around on all the hosts a VM has been migrated to. It
removes the TPM state directory structure from the source host upon
successful migration when non-shared storage is used. Similarly, it
removes it from the destination host upon migration failure when
non-shared storage is used.
