drm/i915/dp: Initialise locals for static analysis 



Just to squelch an smatch warning that doesn't see the with_() being
taken unconditionally:
drivers/gpu/drm/i915//intel_dp.c:230 intel_dp_get_fia_supported_lane_count() error: uninitialized symbol 'lane_info'.
drivers/gpu/drm/i915//intel_dp.c:5338 intel_digital_port_connected() error: uninitialized symbol 'is_connected'.
