hv: PIO emulation handler is attached to I/O port number only

Browse Source 
An I/O handler is not linked to the I/O access size, so in searching for
the registered I/O handler, don't need to check the I/O request's access
size.

In struct vm_io_handler_desc, change fields addr and len to port_start and
port_end respectively to adapt to this change.
