usb: dwc3: meson-g12a: fix refcount leak in dwc3_meson_g12a_resume()

If dwc3_meson_g12a_resume() succeeds in calling
reset_control_reset(), an internal triggered_count reference is
acquired. If any later step fails (usb_init, phy_init,
phy_power_on, regulator_enable, or usb_post_init), the function
returns the error without rearming the reset control. This leaks
the reference and leaves the reset control in a triggered state,
causing future reset_control_reset() calls to incorrectly return
early as if already reset.

Add an error path that calls reset_control_rearm() to balance
the reference before returning the error.
