The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to devm_request_threaded_irq()
(which takes *unsigned* IRQ #), causing it to fail with -EINVAL, overriding
an original error code. Stop calling devm_request_threaded_irq() with the
invalid IRQ #s.
Fixes: f90db10779ad ("usb: dwc3: meson-g12a: Add support for IRQ based OTG switching")
