prman DSO segfaults in AddGeomToParamListBuilderAsFloat

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Export polys as subdives from maya.
2. Make rib with Procedural as usual.
3. Segfaults while copying values to std::vector in ParamListBuilder::addAsFloat

What is the expected output? What do you see instead?
No segfaults

What version of the product are you using? On what operating system?
1.0.5

It looks like AddGeomToParamListBuilderAsFloat calculates wrong boundary for 
array with IV2farray. Attached patch fixes this issue, uvs are rendered ok. No 
segfaults.

With UVs that function gets baseArrayExtent as 2, then multiplies it by 
param.getArrayExtent() to get length of data array, and when calling 
ParamListBuilder::addAsFloat it again multiplies it by param::getExtent().
Fix is just param extent * param array extent.
