Output operators access non-existent members

[manfred-ernst]

operator<<(embree_ostream cout, const PointMi& line) in kernels/geometry/pointi.h accesses the non-existent member line.v0.
operator<<(embree_ostream cout, const QuadraticBezierCurve& a) in kernels/subdiv/bezier_curve.h accesses the non-existent member a.u.

Hi, just fixed this. The fix should be available in the next release.

Thanks!
