[PATCH v2 06/12] drm/bridge: adv7511: Remove a redundant check on existence of bridge->encoder

In the adv7511_connector_init() function, the check on the existence of
bridge->encoder is not necessary. As it has already been checked in the
drm_bridge_attach() which happens prior to the adv7511_bridge_attach()
get called. Also note that the adv7511_connector_init() is only called by
adv7511_bridge_attach(). Hence, it is guaranteed that the .encoder member
of the drm_bridge instance is not NULL when adv7511_connector_init() get
called.

Remove the redundant checking codes "if (!bridge->encoder) { ... }".
