vhost: support interrupt mode
vhost currently supports only polling mode. This patch is to add interrupt mode. When the interface is configured for interrupt mode, our input node does not get called unless there is a packet in the vring. If a particular CPU has one interface configured for polling mode and another in interrupt, the input node is set to polling for that CPU. This diffs also includes two crashes in vlib's dispatch_node. One is included in https://gerrit.fd.io/r/#/c/5516. The other crash is in the ASSERT. The ASSERT can become true when the caller of dispatch_node is in a loop. The first call converted the node to polling. The second call thereafter will hit the ASSERT.
