drm/solomon: Use drm_WARN_ON_ONCE instead of WARN_ON

To prevent log spam, convert all instances to the DRM-specific
drm_WARN_ON_ONCE() macro. This ensures that a warning is emitted only
the first time the condition is met for a given device instance, which
is the desired behavior within the graphics subsystem.
