Salvatore Orlando 830bc5166d Separate NVP create lport operation and neutron db transaction
Bug 1200001

This patch removes the NVP call for creating a logical port from
the SQL transaction context used for creating the Neutron port.
It also ensures orphaned data are properly removed from both
the Neutron DB and the NVP backend.
