Tristan Ye 1989a80a60 Ocfs2: Stop tracking a negative dentry after dentry_iput(). 
I suddenly hit the problem during 2.6.37-rc1 regression test, which was
introduced by commit '5e98d492406818e6a94c0ba54c61f59d40cefa4a'(Track
negative entries v3), following scenario reproduces the issue easily:

Node A			Node B
================	============
$touch 	testfile
			$ls testfile
$rm -rf testfile
$touch 	testfile
			$ls testfile
			ls: cannot access testfile: No such file or directory

This patch stops tracking the dentry which was negativated by a inode deletion,
so as to force the revaliation in next lookup, in case we'll touch the inode
again in the same node.

It didn't hurt the performance of multiple lookup for none-existed files anyway,
while regresses a bit in the first try after a file deletion.
