When running certain HMP commands ("info registers", "info cpustats", "info tlb", "nmi", "memsave" or dumping virtual memory) with the "none" machine, QEMU crashes with a segmentation fault. This happens because the "none" machine does not have any CPUs by default, but these HMP commands did not check for a valid CPU pointer yet. Add such checks now, so we get an error message about the missing CPU instead.
