Currently the cdp apis are given vdev/peer handle as its arguments, which is directly accessed in those APIs. This can cause a race-condition in access of the respective handles if it has been deleted in parallel. Hence as a part of cdp convergence, pass only the vdev_id or peer mac address, which will be used to get the respective handles, and hence avoiding the unwanted access of the handles if it has been deleted. - get_pn_info Change-Id: I410938ed4c3878baa725b6fe3a785cbb99d5fdf4 CRs-Fixed: 2540837
