Clear own_disconnect_req on new connection attempt

It was possible for wpa_s->own_disconnect_req to be left set to 1 from a
disconnection attempt from a prior connection. This could then prevent
proper connection failure processing with the new connection in
wpas_connection_failed(). This was triggered by the following hwsim test
case sequence: wpas_mesh_secure sae_no_ffc_by_default. In this sequence,
the SAE failure due to unsupported group did not result in proper
wpas_connection_failed() processing and retry.

Fix this by clearing wpa_s->own_disconnect_req in
wpa_supplicant_associate() before starting a new connection.
