[PATCH v7 02/16] drm/solomon: ssd130x: Drop the init-only assumption in ssd130x_crtc_create_state()

[Maxime Ripard <mripard@kernel.org>]

The ssd130x_crtc_create_state() implementation warns when the CRTC
already has a state, assuming that atomic_create_state would only ever
be called at initialization time to allocate the initial state.

However, atomic_create_state is documented to have no side effect and
can be called at runtime, so that assumption doesn't hold and the WARN
is a side effect in itself.

Let's drop the WARN, along with the comment documenting that
assumption.
