Jeff Epler e15219800e extmod/modframebuf: Fix crash in scroll() for large inputs. ...

If mp_int_t is wider than int, then the tests such as `xend < 0` can fail
even when the amount of scrolling requested is out of range.  This resulted
in a segmentation fault when attempting an out-of-bounds access to the
framebuffer.
