drm/bridge: Fix a NULL pointer dereference in drm_atomic_bridge_chain_check()
drm_atomic_bridge_chain_check() callers can pass a NULL bridge. Let's
bail out before dereferencing the bridge pointer when that happens.
Reported-by: Chris Wilson <chris@chris-wilson.co.uk>
Fixes: b86d895524ab ("drm/bridge: Add an ->atomic_check() hook")
