Subject: mm/dmapool.c: add WARN_ON() in dma_pool_destroy
The pool is being destroyed so all pages which are in the pool should be
free. If some page is still in use by somebody, we should not just output
error logs, also should also add a WARN message so the stack backtrace may
be used to identify the caller.
