* If during FUSE_CREATE, FUSE_MKDIR, etc the server returns the same
inode number for the new file as for its parent directory, reject it.
Previously this would triggers a recurse-on-non-recursive lock panic.
* If during FUSE_LINK the server returns a different inode number for
the new name as for the old one, reject it. Obviously, that can't be
a hard link.
* If during FUSE_LOOKUP the server returns the same inode number for the
new file as for its parent directory, reject it. Nothing good can
come of this.
