drm/i915/dsi: fix VBT send packet port selection for dual link DSI

commit 5310ec43d6150ab4a2458ba40ecc87bba424433b 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.
