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.
