[DEVMINOR] Changed logs when receiving a command retry
[DEVMINOR] Changed logs when receiving a command retry

On the current version, a warning is emitted each time we refuse a
frame, which can happen either when:
- an out of order frame is received --> a warning is ok
- a retry of the current frame is received --> not an error 'per se',
but a debug log in this case is useful to detect useless retries
