[inbandif] Avoid lldp on inband interface

Signed-off-by: vedganes <vedavinayagam.ganesan@nokia.com>

Changes to avoid LLDP config on Inband interface. Since port type inband
interfaces are recycle ports (or may normal ports) used for asic-to-asic
communication, LLDP is not configured on these interfaces.
