http2: fix transport data race on reused *http.Request objects

Based on golang/go#19653, it should be possible to reuse an http.Request
object after the outstanding request has completed. This CL fixes a race
in the http/2 library that occurs when a caller tries to reuse an
http.Request just after the request completed.

The new test failed with -race before this CL and passes after this CL.
Verified with -count 10000.

Updates golang/go#21316
