drm/exynos: Don't reset bridge->next
[ Upstream commit bd19c4527056b3e42e8c286136660aa14d0b6c90 ]
bridge->next is only points to the new bridge if drm_bridge_attach()
succeeds. No need to reset it manually here.
Note that this change is part of the attempt to make the bridge chain
a double-linked list. In order to do that we must patch all drivers
manipulating the bridge->next field.
