Remove redundant assert of mock volume save call
Remove redundant assert of mock volume save call

Commit 494756c822793f28d69c36e23920ff59809e9a44 added an assert of
mock volume_save call parameters which made an existing assert of mock
volume_save.called redundant. This change removes the old assert from
the libvirt driver test.
