drm/msm/dpu: fix the condition for (not) applying QoS to CURSOR SSPP

The function dpu_plane_sspp_update_pipe() contains code to skip enabling
the QoS and OT limitis for CURSOR pipes. However all DPU since sdm845
repurpose DMA SSPP for the cursor planes because they lack the real
CURSOR SSPP. Fix the condition to actually check that the plane is
CURSOR or not.
