I have no idea why this was here. It makes no sense. If you're trying to find out if something is a directory, why wouldn't you be allowed to ask that about a FIFO? :^) Thanks to Brandon for spotting this! Also, while we're here, cache the directory state in a bool member so we don't have to keep fetching inode metadata when checking this repeatedly. This is important since sys$read() now calls it.
