The _dpu_format_get_plane_sizes_linear() already compares pitches of
the framebuffer with the calculated pitches. Move the check to the same
place, demoting DPU_ERROR to DPU_DEBUG to prevent user from spamming the
kernel log.

Not fully convinced about demoting DPU_ERROR to DPU_DEBUG but I think we 
have had a similar discussion earlier while logging atomic_check 
failures in the CDM series, so keeping that in mind,
