wpa_supplicant: Clear blacklist on connect

It has been noticed that the band steering/load balancing of some
multi-AP networks will lead to an ever-growing list of blacklisted
BSSIDs. This eventually leads to a connection drop when the connection
is pushed to a distant AP.

Fix this issue by clearing the blacklist upon successful connect.
