Cycles: Fix use of uninitialized variable in SSS 

When ray hits curve segment with SSS shader it was possible to have
uninitialized hit_P variable used for sampling.

Seems that was a reason of our headache of difference between AVX2
and SSE4 render results here, so now we can revert all the nasty
ifdef-ed inline policies.
