[NSX-P] Improve port deletion handling

Browse Source 
During port deletion on the backend, we remove profile bindings and
then the actual port. If for any reason a binding is not found, the
process should still proceed to delete remaining resources up to
the segment port.

This change fixes this behaviour, as the code was instead returning
as soon an object was not found.
