BUG/MINOR: backend: Don't increment conn_retries counter too early

Browse Source 
The connection retry counter is incremented too early when a connection
fails. In SC_ST_CER state, errors handling must be performed before
incrementing the counter. Otherwise, we may consider the max connection
attempt is reached while a last one is in fact possible.

This patch must be backported to 2.6.
