Core: don't reuse shared memory zone that changed ownership (ticket #210).

nginx doesn't allow the same shared memory zone to be used for different
purposes, but failed to check this on reconfiguration.  If a shared memory
zone was used for another purpose in the new configuration, nginx attempted
to reuse it and crashed.
