Because we *want* to crash and get a nice backtrace. Since native d3d
crashes when passed a NULL pointer, chances are that if we do get
passed a NULL pParameters here, it is because we passed it to the
application ourselves somewhere earlier. In the case of
GetCreationParameters it's probably not very likely to get passed a
NULL pointer anyway, but that's the general idea.
