So IIUC the issue is being called with num_to_send=0.
Can that happen? Apparently no. Could we assert it is
non-zero?

I kind of prefer to apply the same logic I suggested for walk_gpt():
https://lore.kernel.org/qemu-devel/[email protected]/

i.e., if num_to_send == 0, there is no work to do, so the default value should tell that no error happened. ret = 0 does that.
