IMPALA-15258: Fix race in buffer pool release
target_dirty_bytes in buffer-pool can become negative, which causes the
while loop at the end of CleanPages to never terminate. This appears to
be a race condition in DestroyPageInternal, where we remove the page
from pinned_pages_ while holding lock_, then release the lock and later
update buffers_allocated_bytes_.
