ntfs_link(): prevent creating of recursive directary structure. 

FUSE incorrectly handles case insensitive filesystems: when I try to rename
"/Dir" to "/DIR", ntfsmount receive rename("/Dir", "/DIR/Dir") call.
This patch do not fix rename, but prevent fs corruption. I will mail Miklos
about this problem.
