qcacld-3.0: Do not attempt to delete peer when it is not created

In preassoc state, if the set link state has failed to create the
peer, then send back a failure status to the upper layers and
ensure that the set link state for failure is not called again
because this will eventually call vdev stop and lead to a vdev
stop response and then lead to a peer delete attempt which is
really not needed since the peer has not been created at all.
