spanner: client.Close cancels existing existing createSession calls

When client.Close is called, the invocation blocks until any CreateSession
requests that are currently inflight finish. This CL changes that behavior by
making a client.Close call immediately cancel inflight CreateSession requests.
This generally results in faster Close calls: if CreateSession is hanging it
is dramatically faster.
