From CL 1.2 Section 5.2.1:
CL_INVALID_VALUE if buffer was created with CL_MEM_HOST_WRITE_ONLY and
flags specify CL_MEM_HOST_READ_ONLY , or if buffer was created with
CL_MEM_HOST_READ_ONLY and flags specify CL_MEM_HOST_WRITE_ONLY , or if
buffer was created with CL_MEM_HOST_NO_ACCESS and flags specify
CL_MEM_HOST_READ_ONLY or CL_MEM_HOST_WRITE_ONLY .
Fixes CL 1.2 CTS test/api get_buffer_info
