Subject: [PATCH 1/2] Bridge: fix transfers which ignored host response

Bridge.put() was broken by #2781 because it used transfer() 2-parameters overloaded version, which imply that rxlen == 0.
But the Linux Bridge responded, so the check (i >= rxlen) was true and the function timed out after retrying 50 times.

Every bridge command (python side) has been checked and now SHOULD strictly follow this rule and never ignore silently the received data
