[PATCH v2 3/3] test/graph: fix graph autotest second run test failure

[<kirankumark@marvell.com>]

From: Kiran Kumar K <kirankumark@marvell.com>

The graph autotest second run test is failing due to the
node name is already present in the node list. Adding changes
to free nodes at the time of test cleanup.

Fixes: 6b89650418fe ("test/graph: add functional tests")
