[LogFS] Prevent mempool_destroy NULL pointer dereference
It would probably be better to just accept NULL pointers in mempool_destroy(). But for the current -rc series let's keep things simple. This patch was lost in the cracks for a while. Kevin Cernekee <cernekee@gmail.com> had to rediscover the problem and send a similar patch because of it. :( Signed-off-by: Joern Engel <joern@logfs.org>
