drm/amd/display: Fix null check for pipectx->planestate in hwsssetupdpp
This commit addresses a null pointer dereference issue in
hwsssetupdpp(). The issue could occur when pipectx->planestate is
null. The fix adds a check to ensure pipe_ctx->plane_state
is not null
before accessing. This prevents a null pointer dereference.
