Fix buffer cache pending read statistics by ensuring we can identify
biowait() reads that do *not* come from the buffer cache - we use the
B_RAW flag to identify these at art's suggestion - since it makes sense
and the flag was not being used. this just flags all these buffers with
B_RAW - biodone already ignores returned buffers marked B_RAW.
