This patch uses existing scan results for fast connection after
provisioning.

I have been thinking of doing this. However, it needs to be kept in mind
that the provisioning step can result in the AP changing its
configuration. This happens whenever the AP is in WPS unconfigured
state. As such, I would not do this optimization without first verifying
that WPS state was configured.
