[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. :(
