Log:
voicebus: Only use request_module_nowait on kernels >= 2.6.30.

Request_module_nowait is only useful when asynchronous initialization is used
(committed to trunk in r8094), and that can only happen in kernel version after
2.6.30.  Some earlier kernels do not have the request_module_nowait interface.
