José Expósito 8f069f6dde drm/msm/dpu: invalid parameter check in dpu_setup_dspp_pcc

[ Upstream commit 170b22234d ]

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: 4259ff7ae5 ("drm/msm/dpu: add support for pcc color block in dpu driver")
Addresses-Coverity-ID: 1493866 ("Null pointer dereference")
