iwlwifi: mvm: Increase the scan timeout guard to 30 seconds
commit ced50f1133af12f7521bb777fcf4046ca908fb77 upstream.
With the introduction of 6GHz channels the scan guard timeout should
be adjusted to account for the following extreme case:
- All 6GHz channels are scanned passively: 58 channels.
- The scan is fragmented with the following parameters: 3 fragments,
95 TUs suspend time, 44 TUs maximal out of channel time.
The above would result with scan time of more than 24 seconds. Thus,
set the timeout to 30 seconds.
