Dave LeRoy 2b7e357cf9 nhrpd: cleans up shortcut cache entries on termination 
nhrp_shortcut_terminate() previously was just freeing the associated AFI shortcut
RIBs and not addressing existing shortcut cache entries. This cause a use after
free issue in vrf_terminate() later in the terminate sequence
