Alan Somers 1f44d1861a fusefs: handle evil servers that return illegal inode numbers 
* 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.
