Azat Khuzhin cb578bbe01 Fix possible "nmalloc >= ndalloc" assertion
In arena_stats_merge() first nmalloc was read, and after ndalloc.

However with this order, it is possible for some thread to incement
ndalloc in between, and then nmalloc < ndalloc, and assertion will fail,
like again found by ClickHouse CI [1] (even after #2234).

  [1]: https://github.com/ClickHouse/ClickHouse/issues/31531

Swap the order to avoid possible assertion.

jemalloc is a general purpose malloc(3) implementation that emphasizes
fragmentation avoidance and scalable concurrency support.  jemalloc first came
into use as the FreeBSD libc allocator in 2005, and since then it has found its
way into numerous applications that rely on its predictable behavior.  In 2010
jemalloc development efforts broadened to include developer support features
such as heap profiling and extensive monitoring/tuning hooks.  Modern jemalloc
releases continue to be integrated back into FreeBSD, and therefore versatility
remains critical.  Ongoing development efforts trend toward making jemalloc
among the best allocators for a broad range of demanding applications, and
eliminating/mitigating weaknesses that have practical repercussions for real
world applications.
