i965: Indroduce brw_finish_drawing.

In order to add our ARB_indirect_parameters implementation we
need to refactor brw_try_draw_prims so that it operates on a
per primitive basis and move the loop into brw_draw_prims.
This commit introduces the brw_finish_drawing function where
we move the code that executes once after the loop.
