Bug 1132229: Return in Dispatch method if Bluetooth runnable is nullptr, r=shuang

Browse Source 
With this patch, the dispatch method of Bluetooth runnables simply returns
if the supplied runnable is nullptr. This makes is easy to handle cases
where the caller of a Bluetooth interface method is not interested in the
result.
