virDomainDeviceIsUSB: Handle all USB devices and simplify the code

Rework 'virDomainUSBDeviceDefForeach' to use virDomainDeviceInfoIterate
instead of open-coding all iterators. To achieve this
'virDomainDeviceIsUSB' needs to be fixed as it didn't properly handle
'sound', 'fs', 'chr', 'ccid', and 'net' usb devices.
