drm/amd/display: Fixed kernel panic when booting with DP-to-HDMI dongle
[Why]
In dc_link_is_dp_sink_present, if dal_ddc_open fails, then
dal_gpio_destroy_ddc is called, destroying pin_data and pin_clock. They
are created only on dc_construct, and next aux access will cause a panic.
[How]
Instead of calling dal_gpio_destroy_ddc, call dal_ddc_close.
