[Intel-gfx] [PATCH] drm/i915: Fix the disabling sequence for Bigjoiner

[Stanislav Lisovskiy]

According to BSpec 49190, when enabling crtcs, we first setup
slave and then master crtc, however for disabling it should go
vice versa, i.e first master, then slave, however current code
does disabling in a same way as enabling. Fix this, by skipping
non-master crtcs, instead of non-slaves.
