[PATCH] drm/bridge: Remove a small useless code snippet

[Sui Jingfeng <sui.jingfeng@linux.dev>]

Because the check on the non-existence (encoder == NULL) has already been
done in the implementation of drm_bridge_attach() function, and
drm_bridge_attach() is called earlier. The driver won't get to check point
even if drm_bridge_attach() fails for some reasons, as it will clear the
bridge->encoder to NULL and return a negective error code.

Therefore, there is no need to check another again. Remove the redundant
codes at the later.
