drm/msm/dpu: invalid parameter check in dpu_setup_dspp_pcc
[ Upstream commit 170b22234d5495f5e0844246e23f004639ee89ba ]
The function performs a check on the "ctx" input parameter, however, it
is used before the check.
Initialize the "base" variable after the sanity check to avoid a
possible NULL pointer dereference.
Fixes: 4259ff7ae509e ("drm/msm/dpu: add support for pcc color block in dpu driver")
Addresses-Coverity-ID: 1493866 ("Null pointer dereference")
