Fix behavior of calling RequestStateChange() with DISABLED state...

According to the CIM_EnabledLogicalElement mof, a disabled request should
immediately disconnect the guest.  Currently, the provider calls a shutdown.

This patch changes the behavior so that DISABLED calls virDomainDestroy() and
SHUTDOWN continues to call virDomainShutdown() as expected.
