partial bugfix [#24425] Blender 2.54 Beta crashes when starting rendering

Fix for one of the causes of crashing.
Applying armature deform wasn't thread safe since the pose bones had deform data written into them when deforming a mesh.

This fixes crashing immediately, on every render for me but blender still crashes calculating the subsurf sometimes.
