ubifs: Remove unused security xattr handler

Ubifs installs a security xattr handler in sb->s_xattr but doesn't use the
generic_{get,set,list,remove}xattr inode operations needed for processing
this list of attribute handlers; the handler is never called.  Instead,
ubifs uses its own xattr handlers which also process security xattrs.

Remove the dead code.
