[Ovmsdev] One more WiFi mode off crash

[Michael Balzer]

Greg,

note my note ;) on the earlier fix: there are still lots of simple esp asserts in the Wifi driver.

The standard esp check just panics if the assertion fails, we basically should replace all calls to it by graceful error handling.

Regards,
Michael
