qapi: Rename ChardevBackend member "memory" to "ringbuf"
Commit
1da48c6 called the new member "memory" after commit
3949e59
standardized "ringbuf". Rename for consistency.
However, member name "memory" is visible in QMP since 1.5. It's
undocumented just like the driver name. Keep it working anyway.
