Address a segfault and error introduced in 4b3be09
In the zbegintransparencymaskgroup with a '/None' SMask parameter with the clist
in use, we get to clist_create_compositor().
In there, the return value of the get_cropping method can be either an error
(negative) or a specific cropping operation (positive). We assign it to 'code',
and if it's an error, return it, if not, assign it to another variable. But
don't set 'code' to anything else. It is then possible to get to the end of the
function without going through the path where 'code' is used again.
Setting 'code' to 0 after storing the cropping op solves the problem.
