This patch fixes a deadlock in the fastbin consistency check.
If we fail the fast check due to concurrent modifications to
the next chunk or system_mem, we should not lock if we already
have the arena lock.  Simplify the check to make it obviously
correct.

I don't think the subject line is correct. What is the deadlock? I don't see it.

Thanks,
Florian
