session: avoid debug half-open session pool contention
Half-opens are only allocated from main with worker barrier but can be cleaned up, i.e., session_half_open_free, from main without a barrier. In debug images, the free_bitmap can grow while workers peek the sessions pool, e.g., session_half_open_migrate_notify, and as a result crash while validating the session. To avoid, proactively grow bitmap in debug images. Type: fix Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I2410793f933fb638651fe8dc08ba78e9bee0bd77
