usb: host: ohci-tmio: add IRQ check
The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to usb_add_hcd() (which takes
*unsigned* IRQ #), causing request_irq() that it calls to fail with
-EINVAL, overriding an original error code. Stop calling usb_add_hcd()
with the invalid IRQ #s.
