As part of suggestions to #1801, add NULL CL_MEM_HOST_PTR
check for all flag combinations.

Fixes #1752

The spec requires implementations return NULL for CL_MEM_HOST_PTR
when the flags passed at memory object creation time do not contain
CL_MEM_USE_HOST_PTR

CTS was not checking this. Add the same check.

Fixes KhronosGroup#1752

The change itself looks good to me, though we should close on KhronosGroup/OpenCL-Docs#1008 before merging.
