[PATCH v2 02/12] drm/bridge: tfp410: Remove a redundant check on existence of bridge->encoder

[Sui Jingfeng]

Because the existence of bridge->encoder has already been checked before
the simple_bridge_attach() function get called, And drm_bridge_attach()
will quit with a negative error code returned if it fails for some reasons.
Hence, it is guaranteed that the .encoder member of the drm_bridge instance
is not NULL when the tfp410_attach() function get called.

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