drm/vc4: dsi: Add correct stop condition to vc4_dsi_encoder_disable iteration
vc4_dsi_encoder_disable is partially an open coded version of
drm_bridge_chain_disable, but it missed a termination condition
in the loop for ->disable which meant that no post_disable
calls were made.
Add in the termination clause.
