dpif-linux: Lookup netdev to get netdev type string.
		
When creating tap ports in dpif-linux, the "tap" type is treated the
same as "system", and the type is discarded. When dumping datapath
port types, this would cause "tap" type to be reported as a "system"
type.

Each time we see a port of the wrong type in bridge_reconfigure(), we
remove it and add a port with the correct configuration. This would
always occur for tap ports, causing deletion and re-creation of all tap
ports each time the bridge was reconfigured.

This patch makes dpif-linux use netdev to look up port types if the
datapath reports that they are of type OVS_VPORT_TYPE_NETDEV.

Bug #1196289.
