Peter Hutterer 8b947b4db9 cursor: fix AllocARGBCursor leak/double-free for psrcbits/pmaskbits/argb 
AllocARGBCursor took ownership of the psrcbits/pmaskbits/argb arguments.
But if the initial calloc failed none of them were freed, without the
caller knowing about it. Depending on the code path, those arguments
would thus either leak or be double-freed.

Fix it by always freeing those on error and updating the callers
accordingly.
