Clear reattach flag in fast associate flow

Clear the reattach flags, in case a connection request did not trigger a
scan. This needs to be done to avoid leaving the reattach flag set for
the next scan operation which may not have anything to do with the
specific request that could have been optimized using the single-channel
single-SSID scan.
