[PATCH 3/6] drm/tegra: hdmi: Fix some error handling paths in tegra_hdmi_probe()

[Christophe JAILLET]

If an error occurs after calling tegra_output_probe(),
tegra_output_remove() should be called as already done in the remove
function.

Fixes: 59d29c0ec93f ("drm/tegra: Allocate resources at probe time")
