MEDIUM: stick-tables: Avoid freeing elements while holding a lock

In stksess_trash_oldest(), and process_tables_expire(), avoid freeing
elements while holding two locks, as it could be very costly.
Instead, build a linked list of elements to be free'd, and do so once we
no longer hold any lock.

This may help with github issue #3380, and may be backported to 3.3.
