[libvirt] [PATCH v2 11/15] test: Drop locked access to testDriver->domains

Only self-locking APIs are used and the pointer is immutable so there's
no need to lock the driver to access the domain list.
This patch removes locking partially for everything that will not be
converted to testDomObjFromDomain in the next patch.
