server: break read_from_vdi_port loop if the guest gets disconnected

Browse Source 
read_from_vdi_port calls dispatch_vdi_port data, which will disconnect
the guest agent if it sends invalid data. It would then try to read more
data from the disconnected guest agent resulting in a NULL ptr dereference,
this patch fixes this.
