Because there is no error code for "invalid context" that you can pass to 
alGetString. The closest is AL_INVALID_OPERATION, but it wouldn't make sense 
to return the string for that if the app passed, say, AL_NO_ERROR.

If there's no valid context, alGetString needs to fail. And if alGetString 
fails, it returns NULL.
