uavcan: add warning about CAN error counter reading issue (#26492)

Browse Source 
Add warning message in print_info() to alert users that CAN error counter
values may increase during the function call due to internal counter reading
implementation. Users should not fully trust these counters until the
underlying issue is fixed.
