qcacmn: Add peer APIs to get and release peer ref

The existing peer API cdp_peer_find_by_add does not maintain any peer
references. So a peer which is returned by the API may get deleted in a
different context. This may lead to access to a already deleted memory.

Fix the issue by introducing new APIs "peer_get_ref" and
"peer_release_ref" which make sure the peer is valid until it is
"released" (peer_release_ref is called).
