qcacld-3.0: Tdls avoid peer access after peer deletion

Currently, peer can be accessed after deletion in hdd because
cdp_clear_peer called via tdls_process_del_peer_rsp
tries to remove peer from physical device after deletion of
peer in datapath.

Fix is to remove cdp_clear_peer from hdd as it is handled by
cdp_peer_delete.
