disp: msm: sde: fix panel mode check during secure transition

During transition from sui to non-secure if concurrent
writeback is enabled, it is incorrectly assumed as
video-mode panel. This leads to wrong video-mode
validations and false errors. Fix the check to get the
panel mode only from the primary display.
