[PATCH 3/3] drm/modeset_lock: document trylock_only in kerneldoc

[Daniel Vetter]

I've forgotten to do this in:

commit cb597bb3a2fbfc871cc1c703fb330d247bd21394

    drm: trylock modest locking for fbdev panics

Oops, fix this asap.

In my defense kerneldoc is really awful and there's no way it can pick
up structured comments per struct member. Which means we need both
since people won't scroll up even a few lines.
