In the case of subset decodes, we will often not decode to
the bottom of the image.  In our code before this patch,
this would result in cleanup code in onFinish() never being
called.

We can allow subclasses to take ownership of the
SkScanlineDecoder in order to make sure that it is
finished/deleted before deleting the decode manager.
