chardev: Make the name of memory device consistent 

Now we have memory char device, but the backend name of it
is a little confusion. We actually register it by 'memory', but
the description in qemu-option, the name of open functions
and the new api backend called it 'ringbuf'. It should keep
consistent. This patch named it all to 'memory'.
