runtime: don't free the host_ptr for a subbuffer.
When the buffer has CL_MEM_ALLOC_HOST_PTR, the runtime
need to free the host_ptr at destructor. But if the buffer
is a subbuffer, then its host ptr is not allocated by itself,
we should not free it here. Otherwise, it may cause
some weird errors such as:
"corrupted double-linked list..".
