when call cbCreateSubBuffer when followings memory flags are not set
they should be inherited from parent buffer.
Report them when calling clGetMemObjectInfo
flags:
CL_MEM_READ_WRITE, CL_MEM_READ_ONLY, CL_MEM_WRITE_ONLY,
CL_MEM_USE_HOST_PTR, CL_MEM_ALLOC_HOST_PTR, CL_MEM_COPY_HOST_PTR,
CL_MEM_HOST_WRITE_ONLY, CL_MEM_HOST_READ_ONLY, CL_MEM_HOST_NO_ACCESS
