Fix T44691 Freestyle render crashes when Views is on (Blender Internal).

In pipeline.c the function add_freestyle() was supposed to be called once
per frame, but after the Multi-view merge the function are called as many
as the number of views.  There were however a few Freestyle parameters
that have to be initialized per frame, and initializing one of the
parameters for each view was causing double freeing of allocated memory
which was enough to result in a crash.
