drm: vkms: Replace hardcoded value of `vkms_composer.map` to DRM_FORMAT_MAX_PLANES 

The `map` vector at `vkms_composer` uses a hardcoded value to define its
size.

If someday the maximum number of planes increases, this hardcoded value
can be a problem.

This value is being replaced with the DRM_FORMAT_MAX_PLANES macro.
