[release-branch.go1.15-bundle] http2: close Transport connection on write errors

When a new connection is created, and a write error occurs during the
initial exchange, the connection must be closed. There is no guarantee
that the caller will close the connection.

When a connection with an existing write error is used or being used, it
will stay in use until its read loop completes. Requests will continue
to use this connection and fail when writing its header. These
connections should be closed to force the cleanup in its readLoop.

Updates golang/go#39337.
For golang/go#42113.
