Fix below GPU stats collection since D52063174 broke it

Summary:
GPU stats collection is broken. User report:
https://fb.workplace.com/groups/505463673566896/permalink/1501842497262337/

Looking at logs, looks like it's related to tokio/srclient: P944160448.

D52063174 affectively forces us to use tokio runtime. This is not the
first time is has happened (see
https://fb.workplace.com/groups/rust.language/posts/6113510662030831/?comment_id=6140563555992208).
