dcache: don't clear DCACHE_DISCONNECTED too early 



DCACHE_DISCONNECTED should not be cleared until we're sure the dentry is
connected all the way up to the root of the filesystem.  It *shouldn't*
be cleared as soon as the dentry is connected to a parent.  That will
cause bugs at least on exportable filesystems.
