I accidentally moved the bo->bufmgr dereference above the NULL check
when cleaning up this code.
While passing NULL to free() is a common pattern...passing NULL to
unmap seems pretty bad. You really ought to know whether you have
a buffer or not. We don't want to paper over bugs like that. So,
just drop the NULL check altogether.
