Currently, VDEV manager responses are using legacy path instead of target_if, vdev_mgr and os_if components. As the driver implementation is planned for converged model, legacy implementation will be moved to the respective components. To avoid rework, Use target_if, vdev_mgr and os_if components to process the FW responses corresponding to the vdev manager. Change-Id: I778f6de93481fc730383e8f8e1c604f173947d69 CRs-Fixed: 3093776
