Miguel Angel Ajo e082336968 Don't delete flows on ports which were on dead vlan during plug 
Ocata codebase of the neutron agent deletes_flows
when a port has been tagged and already had a tag.

Later versions implement uninstall_flows to selectively delete
specific flows, but such patches are big and buggy (have several
follow up patches).

This prevents that the patch handling 1767422 will get the DSCP
flows deleted when port is tagged. Which is detected by functional
testing.

I have manually tested that setting a port admin_state_up False,
and then True, will correctly move the port into dead vlan, and
then back to non dead vlan, and properly remove the in_port=x,DROP
openflow rule regardless of this change.
