http2: don't return from RoundTrip until request body is closed

Moving the Request.Body.Close call out from the ClientConn mutex
results in some cases where RoundTrip returns while the Close is
still in progress. This should be legal (RoundTrip explicitly allows
for this), but net/http relies on Close never being called after
RoundTrip returns.

Add additional synchronization to ensure Close calls complete
before RoundTrip returns.

Fixes golang/go#55896
