Remove unused ScrollAnimatorNone::PerAxisData constructor argument.

Remove unused ScrollAnimatorNone::PerAxisData constructor argument.

The 'parent' argument is not used, remove it.

This implicitly fixes an incorrect invocation of the constructor from
ScrollAnimatorNoneTest::SavePerAxisData, which following r183583 was
passing in an uninitialized pointer value as argument.

Based on that thread, and the fact that everything still seems to work, LGTM.
Thanks for cleaning this up.
