conf,qemu: Check for NULL addrs in virDomainUSBAddressRelease

Browse Source 
Rather than having the caller check, if the input @addrs is NULL
(e.g. priv->usbaddrs), then just return 0. This also removes the
need for ATTRIBUTE_NONNULL which only really helped if someone
passed a NULL as a parameter not if the passed parameter is NULL.
