o bugfix
- get a removed dentry from an inode, reported by Andrew Vagin
In aufs, there are several places getting a dentry from an inode.
It can happen that all names are unlinked and only the inode is still
alive. In this case, d_find_alias() doesn't return any dentry and aufs
cannot find the dentry, so it simply returns an error. It is ok in most
cases. but in some cases, aufs should search a dentry even if it was
unlinked. For these cases, replace them by d_find_any_alias() which can
return a removed dentry.
This problem was found by Andrew Vagin using inotify00 test program in
