drm/i915/dsi: fix VBT send packet port selection for dual link DSI
commit f9cdf4130671d767071607d0a7568c9bd36a68d0 upstream. intel_dsi->ports contains bitmask of enabled ports and correspondingly logic for selecting port for VBT packet sending must use port specific bitmask when deciding appropriate port.
