Johan Hovold 2e786eb2f9 drm/msm/dsi: fix memory corruption with too many bridges 
Add the missing sanity check on the bridge counter to avoid corrupting
data beyond the fixed-sized bridge array in case there are ever more
than eight bridges.

Fixes: a689554ba6 ("drm/msm: Initial add DSI connector support")
