use g_ prefix on the global. 

Place the global into an anonymous namespace.
https://www.chromium.org/developers/coding-style#TOC-Unnamed-Namespaces

Move to top of .cc file -- we expect statics and globals at top.

I should have made these comments in
https://codereview.chromium.org/1646023002#msg10 sorry, but please fix up
bluetooth_low_energy_win.cc also.
