Subject: [PATCH] lib: Don't force the key argument when deleting metadata

virDomainSetMetadata when operating on the metadata element was
requesting the @key argument to be passed even if @metadata was NULL
used to delete the corresponding metadata element. This is not needed as
the key is only used when adding the element and matching is done via
the XML namespace.
