[libvirt] [PATCH] Resolve Coverity complaint in storagevolxml2argvtest

[Ján Tomko]

Ignore NULL pool in testSetVolumeType to silence Coverity,
even though we only call it with NULL pool when vol is also NULL.

(13) Event var_deref_model:	Passing null pointer "inputpool" to
function "testSetVolumeType(virStorageVolDefPtr, virStoragePoolDefPtr)",
which dereferences it. [details]
Also see events: [assign_zero]

95    testSetVolumeType(inputvol, inputpool);
