The message here was unclear. The sole caller of __glXDRIcontextWait
ignores the error value, so it doesn't matter what we assign to *error
here.

noClientException is legitimately used by the dispatch loop for failure
conditions (failure to alloc a protocol output buffer eg). That could
probably be cleaned up further, sure.
