Azat Khuzhin 78b58379c8 Fix possible "nmalloc >= ndalloc" assertion.
It is possible that ndalloc will be updated before nmalloc, in
arena_large_ralloc_stats_update(), fix this by reorder those calls.

It was found by ClickHouse CI, that periodically hits this assertion [1].

That issue contains lots of examples, with core dump and some gdb output [2].

Here you can find binaries for that particular report [3] you need
clickhouse debug build [4].

Brief info from that report:

            ndalloc = 226
            nflush = 0
            curlextents = 0
            nmalloc = 225
            nrequests = 0

Here you can see that they differs only by 1.

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.
