http2: remove conn->data usebagder/h2-conn-data

Starting here, the code sets the 'data' pointer as user-data even for
the connection, and the callbacks need to find the connection using
'data->conn'. Since the transfer can come and go over the life time of
the connection it thus becomes important to always set the correct
"current transfer" when calling nghttp2 so that it doesn't get the *old*
transfer that previously used the connection.
