OWE: Update transition mode information on selecting a new BSS

It is possible for a new BSS entry to be added for the
hidden-SSID-OWE-BSS when running a new scan after having previously
learned the hidden SSID during a previous OWE connection attempt. That
new entry would not necessarily have the WPA_BSS_OWE_TRANSITION flag set
and that would result in not being able to recognize the appropriate OWE
profile when checking the association event against the transition mode
configuration.

Fix this by updating the BSS entry for OWE transition mode information
for the cases where this might happen.
