st/nine: Fix leak with integer and boolean constants

Leak introduced by:
a83dce01284f220b1bf932774730e13fca6cdd20

The patch also moves the part to
release changed.vs_const_i and changed.vs_const_b
before the if (!cb.buffer_size) check,
to avoid reuploading every draw call if
integer or boolean constants are dirty, but the shaders
use no constants.
