Cherry-pick: Don't write errors to dummy sessions

Browse Source 
If a DCB is closed before a response to the handshake packet is received,
the DCB's session will point to the dummy session. In this case no error
should be written to the DCB.

This is a cherry-pick of commit f53e112bf49766f1cc55516c2d7ee571461d483f
from the 2.2 branch.
