drm/amd/display: Move drm_get_vblank from legacy code
Previously, we assumed that allow_modeset=false => page flip. This
assumption breaks when an atomic commit is submitted with allow_modeset
set to false, since the legacy flip code is never called (the legacy
code grabs the vblank reference).
Fix: Move drm_vblank_get() from amdgpu_atomic_helper_page_flip() to
amdgpu_dm_commit_surfaces().
