The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to devm_request_irq() (which takes
*unsigned* IRQ #), causing it to fail with -EINVAL, overriding an original
error code. Stop calling devm_request_irq() with the invalid IRQ #s.
Fixes: 8b2e76687b39 ("USB: AT91 UDC updates, mostly power management")
