* @summary This test verifies whether setting the order reversely between 2 spi
* objects removes the previous ordering that was set between the
* same set of spi objects. This is verified by invoking
* unsetOrdering() method twice consecutively with respect to the same
* spi objects and unsetOrdering() is supposed to return false when
* called for the second time.
