lib/stackdepot: fix and clean-up atomic annotations

Drop smp_load_acquire from next_pool_required in depot_init_pool, as both
depot_init_pool and the all smp_store_release's to this variable are
executed under the stack depot lock.

Also simplify and clean up comments accompanying the use of atomic
accesses in the stack depot code.
