OWE: Optimize transition mode AP scan with owe_only=1 STA configuration

Browse source 
Extend the optimization from commit 9c97126576 ("OWE: Optimize
transition mode scan to use known channels") to cover cases where the
STA is configued with OWE transition mode disabled, but the AP uses OWE
transition mode.
