[igt-dev] [i-g-t V2 3/3] tests/kms: Add missing igt_put_cairo_ctx()

[Bhanuprakash Modem]

Remeber to call igt_put_cairo_ctx() after rendering to make
sure the results actually end up in the framebuffer (in case
the rendering happens to a temporary buffer and there needs
to be a copy back at the end).
