SME: Optimize recovery from common load balancing mechanisms

When authentication or association fails when trying to connect to
a BSS in an ESS that has multiple BSSes based on previous scans,
limit the first recovery scan to only the known channels that has
been seen previously. This speeds up recovery in some of the most
commonly used load balancing mechanisms in enterprise WLAN
networks.
