MINOR: pools: call malloc_trim() under thread isolation
pool_gc() was adjusted to run under thread isolation by commit c0e2ff202
("MEDIUM: memory: make pool_gc() run under thread isolation") so that the
underlying malloc() and free() don't compete between threads during these
potentially aggressive moments (especially when mmap/munmap are involved).
Commit 88366c292 ("MEDIUM: pools: call malloc_trim() from pool_gc()")
later added a call to malloc_trim() but made it outside of the thread
isolation, which is contrary to the principle explained above. Also it
missed it in the locked version, meaning that those without a lockless
implementation cannot benefit from trimming.
This patch fixes that by calling it before thread_release() in both
places.
