usb: gadget: fusb300_udc: free irq on the error path in fusb300_probe() 

When request_irq(ires1->start) failed in w5300_hw_probe(), irq
ires->start has not been freed, and on the clean_up3 error path,
we also need to free ires1->start irq, fix it.

In addition, We should add free_irq in fusb300_remove(), and give
the lables a proper name so that they can be understood easily,
so add free_irq in fusb300_remove(), and update clean_up3 to
err_alloc_request.
