[PATCH] qbsp: Fix warning about invalid wads

Add back the warning message about invalid wads. Don't bother to differentiate
between filesystem errors and bad magic, etc. The file is already open, so if
we can't read it's either too small or there might be some hardware problem
(not worth dealing with separately).
