Jouni Malinen 64766a7783 tests: Make TDLS test case scan clearing more robust
There was a race condition on starting the flush_scan_cache() operations
if a scan happened to be in progress when the test case ended since the
ABORT_SCAN success case did not wait for the pending scan operation to
be completed. Wait for the scan completion event in addition to the
disconnection event if the ABORT_SCAN command is accepted.
