dix: be more verbose when we run out of opcodes

Browse Source 
If we run out of opcodes, nothing is print on the log, making the
problem hard to debug. In the current Xserver, if you enable some
extensions like multibuffer (+2 events) and use nvidia binary driver (+5
events) you can run out of opcode numbers.
