drm: Add a non-locking version of drm_kms_helper_poll_enable(), v2
drm_kms_helper_poll_enable() was converted to lock the mode_config mutex in commit 8c4ccc4ab6f64e859d4ff8d7c02c2ed2e956e07f ("drm/probe-helper: Grab mode_config.mutex in poll_init/enable"). This disregarded the cases where this function is called from a context where this mutex is already locked. Add a non-locking version as well. Changes since v1: - use function name suffix '_locked' for the function that is to be called from a locked context.
