disp: msm: sde: fix inline rotator downscale ratio check

During the validation of inline-rotator downscale ratio,
in the plane atomic_check phase, the client_type is
derived from the crtc->state. This leads to wrong
client_type as in check phase, it has to be derived
from the new crtc state. Fix it to derive from
new crtc, which would in turn be used to get the
correct inline-rotator downscale ratio.
