always check if the directory entry qid from the loc still matches the one on disk before doing anything. helps catching bugs and is basically equivalent to what cwfs does with its checktag. make a haveloc() check in newentry() to make sure we dont allocate a file slot thats still in use, but deleted. this seems to fix the NPROC>1 build problems.
