Bugfix in routing logic to avoid null groups; Improvement in group handling.
Two main changes for the bug-fix:
- avoid doing a full-reroute in the event of link failure as this will leave behind stale state in stores
if event has been preceded by mastership change leading to the nuking of the ecmpSpg for one of the
link's devices; instead do a rehash
- when full-reroute is attempted, do it only once, with a complete nuke of the next-obj store
Improvement in group handling allows for a max number of retries for a group that failed to be added.
Earlier behavior was to try only once, and if it fails, it gets removed from the group-store. Now it
is removed after a couple of retries - so total 3 attempts to program the group.
