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

Browse source

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

Move bridge registration before the IRQ is requested and route bridge
registration failures through the existing TCPM unregister and fwnode
cleanup path.
