dlist: don't handle unmerged draws as merged

Browse source 
The comment was incorrect: we can have N draws using the
same mode with N > 1 (eg: GL_QUAD_STRIP draws
cannot be merged).

This commit fixes the drawing code to use the correct draw
function.

This fixes a hang in Starsector (see issue #5086).

Fixes: b328d8e9bc ("dlist: use an union instead of allocating a 1-sized array")
