  dialog: Fix missing unlock ops on DB load error-cases

This patch fixes some startup deadlocks in case a dialog loaded from
database has an incorrect DID (failed checksum check) or if OpenSIPS
runs out of shared memory while importing dialogs from DB on startup.

(cherry picked from commit 9e8d36c34390d18d5996121deddcce5cd143830f)
