[PATCH 2/2] drm: fix kernel-doc struct tag for `drm_modeset_lock`.

[Javier Garcia]

- Add needed "@" to avoid warn messages about duplicated symbols
as there is function and struct with the same name.
- The fixed warning is:

	./Documentation/gpu/drm-kms:476: ./drivers/gpu/drm/drm_modeset_lock.c:377: WARNING: Duplicate C declaration, also defined at gpu/drm-kms:48.
	Declaration is '.. c:function:: int drm_modeset_lock (struct drm_modeset_lock *lock, struct drm_modeset_acquire_ctx *ctx)'. [duplicate_declaration.c]

Fixes: f3a808817fdb ("drm: fix drm_modeset_lock.h kernel-doc notation")
