nhrpd: Cleanup resources when interface is deleted
Currently when an interface is deleted from configuration, associated
resources are not freed. This causes memory leaks and crashes.
To reproduce this issue:
* Connect to a DMVPN hub
* Outside of frr, delete the underlying GRE interface
* Use 'no interface xxx' to delete the interface containing nhrp configurations
