Pass the appropriate PortModInput to portMod

Pass the appropriate PortModInput to portMod

In ModelDrivenSwitchImpl we were building an input but the built input was not passed to portMod. This had issues like missing Xid on the PortModInput
which caused NPE's downstream in the open flow java code

Also we were not correctly population ConfigV10, MaskV10 and FeaturesV10 on the PortModInput which caused NPE in the open flow java code when using
open flow 10

This commit fixes both of those problems. After this updatePort actually works.
