[Freedreno] [PATCH 12/25] drm/msm/dpu: remove mode_set_complete

[Jeykumar Sankaran]

This flag was introduced as a fix to notify modeset complete
when hw reservations were happening in both atomic_check
and atomic_commit paths. Now that we are reserving only in
atomic_check, we can get rid of this flag.
