[Freedreno] [PATCH 1/4] drm/msm/dpu: avoid checking uninitialized plane format

[Abhinav Kumar]

dpu_plane_atomic_check() checks for the format to make sure its
not YUV before using multirect.

However the format is not initialized before this. This causes
a compilation issue and also would not work if YUV content
is tried.

Fix it by setting the format before the check.
