Log:
Fix for a race between lookup and readdirplus, that causes
a deadlock (with NFS exclusive vnode locks enabled). Lookup
grabs the parent's lock and wants to lock child. Readdirplus
locks the child and wants to lock parent (for loading the attrs
for ".."). The fix is to not load the attrs for ".." in
readdirplus.
