map: use SVR for MAP-T
This change is part of an effort to unify reassembly code. By removing shallow virtual reassembly functionality in MAP and using the common vnet provided shallow virtual reassembly, code size and complexity is reduced. Type: refactor Change-Id: Iec8edd039f7b967b53e17bb9bca228a8b452ac0c Signed-off-by: Klement Sekera <ksekera@cisco.com>
