msm: kgsl: use %pK to restrict printing GPU / memory addresses 



Use %pK in the output for the per-process memory dump to keep from
printing the GPU and user memory addresses for the GPU memory
objects own by the process.  This allows us to make the 'mem' file
world readable without exposing any really dangerous information.
