RDS: Rewrite rds_send_xmit
Simplify rds_send_xmit(). Send a congestion map (via xmit_cong_map) without decrementing send_quota. Move resetting of conn xmit variables to end of loop. Update comments. Implement a special case to turn off sending an rds header when there is an atomic op and no other data. Signed-off-by: Andy Grover <andy.grover@oracle.com>
