drm/vc4: crtc: Remove manual plane removal on error

When vc4_crtc_bind() fails after vc4_crtc_init() has been called, we have
a loop undoing the plane creation and calling destroy on each plane
registered and matching the possible_crtcs mask.

However, this is redundant with what drm_mode_config_cleanup() is doing, so
let's remove it.
