Why is this non-const param first?

[sandersd (OOO until July 31), 2015/03/06 22:36:58]

Presumably for symmetry with CdmSessionAdapter::Initialize(). Ideally it would
be const, but CdmFactory::Create is not a const method (I can't imagine why it
would need to be mutable though).

I can move it down in this CL, but the reality is that it's treated as const,
and if it were const it is already in the right place.
