Remove NULL Platform Check for Negative clGetPlatformInfo (#1222) (#1229)

Part of the negative CTS test for clGetPlatformInfo
incorrectly tested with a NULL platform. As this is a
special case it meant that the test was not correct.
This change removes the incorrect part of the test so that
it conforms with the OpenCL specification.
