[PATCH] usb: typec: fusb302: Fix resource leak when devm_drm_dp_hpd_bridge_add() fails

[Felix Gu]

If devm_drm_dp_hpd_bridge_add() fails during fusb302_probe(), the original
code returned directly without cleaning up the resources.

Route the failure through the existing unwind path so probe cleans up the
same resources that are released in remove().
