    conn: Stop writing when our write bandwidth limist is exhausted · 2000d04c

    Commit 488e2b00 introduced an issue, most
    likely introduced by a bad copy paste, that made us stop reading on the
    connection if our write bandwidth limit was reached.
    
    The problem is that because "read_blocked_on_bw" was never set, the connection
    was never reenabled for reading.
    
    This is most likely the cause of #27813 where bytes were accumulating in the
    kernel TCP bufers because tor was not doing reads. Only relays with
    RelayBandwidthRate would suffer from this but affecting all relays connecting
    to them. And using that tor option is recommended and best practice so many
    many relays have it enabled.
    
    Fixes #28089.
