nit: just use associated_interfaces_

[sadrul, 2017/01/23 19:57:49]

I tried that at first, but it gives me a compile error:

../../content/gpu/gpu_child_thread.cc:222:26: error: too few arguments to
function call, expected 2, have 1; did you mean
'AssociatedInterfaceRegistry::AddInterface'?
  associated_interfaces_.AddInterface(base::Bind(
                         ^~~~~~~~~~~~
                         AssociatedInterfaceRegistry::AddInterface
../../content/public/common/associated_interface_registry.h:36:16: note:
'AssociatedInterfaceRegistry::AddInterface' declared here
  virtual void AddInterface(const std::string& name, const Binder& binder) = 0;


I have to use:

 
associated_interfaces_.AssociatedInterfaceRegistry::AddInterface(base::Bind(...

to fix the build error, which feels rather awkward. So I have kept it as is for
now (although maybe there's a cleaner magic incantation I could use?)
