usb: gadget: amd5536udc: fix error handling in udc_pci_probe()

If a failure happens early in udc_pci_probe(), error handling code
just kfree(dev) and returns. The patch adds proper resource
deallocations in udc_pci_probe() itself,
since udc_pci_remove() is not suitabe to be called so early
in initialization process.

By the way, iounmap(dev->regs) is replaced by iounmap(dev->virt_addr)
in udc_pci_remove() for clarity.
