clang complains it doesn't initialize const member, so this CL calls the
default constructor explicitly.

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/1577323005/ by dongseong.hwang@intel.com.

The reason for reverting is: This issue is known in crbug.com/506663 and we want
to fix c++ spec and clang rather than making chromium code silly.
Nico asked to revert it..
