Devices: 56980_A0,56980_B0,AllChips
Module: ALPM

Symptom:
ALPM: Parallel Mode: DEFAULT_MISS=1: Packets gets dropped due to dest
miss even if a matching route exists in the database

Fixed mistake in previous change SDK-177481, where PVT_BKT_DEF(pvt_node)
for Level2 is using wrong pvt_node from Level1. Solution is:  1.) Add
default_miss argument in lpm_cfg, and when init, insert or update a
pvt_node, indicate default_miss and set properly in HW for Parallel and
TCAM mixed mode.   2) Add default_miss sanity check for both positive or
negative cases.
