[PATCH] drm/vblank: Fix a name that does not exist in kernel-doc

[Karl Mehltretter]

The kernel-doc comment of
drm_crtc_vblank_helper_get_vblank_timestamp_from_timer() refers to
drm_crtc_helper_get_vblank_timestamp_from_timer, which does not exist.
The name is drm_crtc_vblank_helper_get_vblank_timestamp_from_timer. Say
drm_crtc_vblank_helper_get_vblank_timestamp_from_timer.

Fixes: 74afeb812850 ("drm/vblank: Add vblank timer")
