damage: Simplify DamageUnregister

Browse Source 
You can only register one drawable on a given damage, so there's no
reason to require the caller to specify the drawable, the damage is
enough.  The implementation would do something fairly horrible if you
_did_ pass mismatched drawable and damage, so let's avoid the problem
entirely.
