[libvirt] [PATCH 5/6] storage: Unlink stateFile in storagePoolSetInactive

[Cole Robinson]

There are several places in the storage driver where a runtime
stateFile is not being unlinked when the pool is shutdown. Move
the unlinking to storagePoolSetInactive to fix those locations

One minor semantic change is that we no longer fail PoolDestroy
if we fail to build the stateFile path string, but I don't think
that matters.
