qcacld-3.0: Do not send reassoc failure in case of no hw_mode change

In roaming scenario when there is no hw_mode change is required, roam
failure is sent to CSR which is causing move VDEV from INIT state to
EV_DOWN. In this case, wma_target_req buffer expected instead of
scheduler_msg. As the wrong buffer is passed, it is causing a
system instability.

Fix is not to send reassoc failure for LFR2 when there is
no change in hw_mode required and go ahead with connect.
