mempool: Reduce an assert into an error return for get_buddy()

If we ask for a buddy that is outside of our allocation that is an
error that should not happen with a power-of-two allocated zone...
However, since it has been seen in the wild, we can safely return that
there is no buddy rather than die in a too-late assert.
