Be backwards compatible with diameter_sctp listener state
Be backwards compatible with diameter_sctp listener state

Commit 24993fc2 modified the state even in the case that the new
pool_size option the change was introduced to support was not used.
Doing so made downgrade impossible since old code would not be prepared
for the modified state. Retain a compatible state, so that simple code
replacement is enough.
