The rekey/reauth logic was broken in a few different ways.
For rekeys the event list was not being reset so any past 4-way
handshake would allow the call to pass. This actually removes
the need for the sleep in the extended key ID test because the
actual handshake event is waited for correctly.
For both rekeys and reauths, just waiting for the EAP/handshake
events was not enough. Without checking if the client got
disconnected we essentially allow a full disconnect and reconnect,
meaning the rekey/reauth failed.
Now a 'disallow' array can be passed to wait_for_event which will
throw an exception if any events in that array are encountered
while waiting for the target event.
The test was rekeying in a loop which ends up confusing hostapd
depending on the timing of when it gets the REKEY command and any
responses from IWD. UML seemed to handle this fine but not QEMU.
Instead delay the rekey a bit to allow it to fully complete before
sending another.
