compositor: forbid sub-surface nesting loops

The only way to create a sub-surface loop by recursive nesting is to
make the main surface (which does not have a role) a sub-surface of any
of its sub-surfaces. All other cases should already be cought.

This change checks for that exact case, and sends a protocol error.
