http2: refund connection flow control on DATA frames received after reset

If the transport had previously sent a RST_STREAM but had not yet
deleted the stream from its list of active streams, we should refund
connection-level flow control for any DATA frame received as such
DATA frames will never be read.

We already refund connection-level flow control if a stream closes with
unread data in bufPipe. However, when we receive a DATA frame after
reset, we don't bother writing it to bufPipe, so we have to refund the
flow control separately.

Updates golang/go#20469
