Problem: https://github.com/ceph/ceph/blob/eba596dfc87176b2236b77f39a0ee3c80f37ba37/src/test/libcephfs/test.cc#L373

If the randvar r is 0, then the buffer length told to ceph_getdents is 0. The buffer is sized properly here:

https://github.com/ceph/ceph/blob/eba596dfc87176b2236b77f39a0ee3c80f37ba37/src/test/libcephfs/test.cc#L368

but we didn't pass the right length.
