remus: fix incorrect error handling for switch_qemu_logdirty in checkpoint code

c/s 22275: "tools: cleanup domain save switch_qemu_logdirty callback"
introduced a whole bunch of error code fixups. In the process, it also
ended up treating the success return code (0) from
switch_qemu_logdirty as an error and vice versa.
