qcacld-3.0: Send the correct error to HDD if self peer creation fails

During the vdev attach if the self peer creation fails from the protocol
stack the correct vdev delete is sent to the firmware but the success error
is propogated back to the HDD and the wmi vdev set commands are sent
to the firmware with invalid vdev id.
