[PATCH v2 3/3] qemu_tpm: do not delete parent directory for custom source

[marcandre.lureau@xxxxxxxxxx]

From: Marc-André Lureau <marcandre.lureau@xxxxxxxxxx>

When the vTPM source path is specified, such as:
   <source type=".." path="/my/tpm"/>

Do not delete the parent directory, but only the given file/dir.

Fixes: commit f1304cc566 ("qemu_tpm: handle file/block storage source")
