Subject: [PATCH] tty: Make driver-side flip buffers lockless

Driver-side flip buffer input is already single-threaded; 'publish'
the .next link as the last operation on the tail buffer so the
'consumer' sees the already-completed flip buffer.

The commit buffer index is already 'published' by driver-side functions.
