qcacld-3.0: Fix NULL VDEV pointer during register in monitor mode

After gerrit#2436786(which the Change-ID is
Ie64a05d795660d557d928cb9b874fa5e702f4f55), vdev in monitor mode
is removed from vdev list of pdev. So it is needed to use the new
cdp api, which is cdp_get_mon_vdev_from_pdev instead of
cdp_get_vdev_from_vdev_id in monitor mode to register vdev.

CRs-Fixed: 2350720
Change-Id: Idd36cdb09666783db2042f77708be4dcc6b9d82b
