Thomas Zimmermann 3d379b2a73 drm/ast: Fix comment on modeset lock 
commit 7cce65f378 upstream.

The ast driver protects the commit tail against concurrent reads
of the display modes by acquiring a lock. The comment is misleading
as the lock is not released in atomic_flush, but at the end of the
commit-tail helper. Rewrite the comment.
