kernel route table introspect shows duplicate entries

[Vedamurthy Joshi]

Pls see attachment.

The routes are shown across multiple tables
It seems that last entry of one table and the first entry of its next table are the same.

The rt utility also shows duplicate entries .

root@nodec17:~# rt --dump 1 | grep 20.0.0.12
20.0.0.12/32 0 - 0 -
20.0.0.12/32 0 - 0 -

Dont display last displayed route in rt dump

Mtrie dump, dumps 32 routes per one iteration. "rt" utility sends last displayed
route in rt_marker in the next iteration. Vrouter searchs till rt_marker and
starts displaying the routes again from rt_marker. This results in rt_marker
being displayed in previous and as well as current iteration.

As such rt_marker_plen is not being used while searching the rt_marker. So the
usage of this is removed in Vrouter. Sandesh file is not changed so that
Agent does not have to undergo any further changes.
