[Ovmsdev] CAN errata fix regression?

Craig, everyone,

one of the ESP32CAN errata fixes seems to have caused a regression.

I now frequently see this log message:

esp32can: TxCallback: fatal error: TX buffer not available

Meaning there was a TX buffer free interrupt, but the TX buffer status 
did not match that. I never saw this message before the errata fixes.

Do others see this message?
