[lacp] Ignore (and do not echo) trailing padding on received packets
...
The LACP responder reuses the received I/O buffer to construct the
response LACP (or marker) packet. Any received padding will therefore
be unintentionally included within the response.
Truncate the received I/O buffer to the expected length (which is
already defined in a way to allow for future protocol expansion)
before reusing it to construct the response.
