Prevent recording race-condition when wifi is enabled

[SumolX]

Resolves issue #432 where recording is initiated before wifi configuration has completed. This is breakage introduced due to boot up optimization.

Tested with an eco vtx, 3 flights, all correctly recorded, wifi enabled.

Flashed and tested it, goggles are set to Auto Scan -> Default: Last

When my goggles are booted up using analog, start recording, the problem still persists with the DVR scaling. After going through the menu and back to recording analog, it is properly scaled. So for my scenario it is not yet solved.

For what it's worth, after I switched WiFi to OFF, the issue does no longer show up. Switching it back to ON, and the issue is back.

I am still working on it and will supply a proper fix. Root cause has been identified in regards to the race condition.
