disp: msm: update seamless check for cwb + any modeset

Browse Source 
When there is CWB enablement + dynamic clock change request in
single commit, during modeset enables the cwb seamless check
is hit for primary connector causing bridge pre enable
and enable calls skipped for dsi connector. This change ensures
the above seamless transition is taken care with any modeset case
as well.
