From: Shaul Triebitz <shaul.triebitz@xxxxxxxxx>
Canceling the periodic timestamp work should be
done in the opposite flow to where it was started.
This also prevents from sending the MARKER command
during the mac_stop flow - causing a false queue hang
(FW is no longer there to send a response).
Fixes: 93b167c13a3a ("iwlwifi: runtime: sync FW and host clocks for logs")
