CL 432038 reduces sending WindowUpdates by introducing a threshold. Once
the remaining bytes are below the threshold, a single WindowUpdate is
sent to reset the amount back to the maximum amount configured.
The window increment size for a stream is calculated from:
sc.srv.initialStreamRecvWindowSize() - st.inflow.available()
Where (*flow).available is defined as:
func (f *flow) available() int32 {
n := f.n
if f.conn != nil && f.conn.n < n {
n = f.conn.n
}
return n
}
When f.conn.c < f.n, it gets a bigger increment size. It should be
calculated from:
sc.srv.initialStreamRecvWindowSize() - st.inflow.n
While we're here, remove an unnecessary type conversion too.
Updates golang/go#56315.
