Originally, after adding a RXE device successfully, the RXE device
gets ready, it still reports 'PORT_DOWN' state. Set the state to
*IB_PORT_ACTIVE* once it becomes ready to access.
IB_PORT_ACTIVE is set in the function rxe_port_up.
The followings are the call chain.
rxe_net_add -- > rxe_register_device -- > ib_register_device -- >
enable_device_and_get -- > rxe_enable_driver -- > rxe_set_port_state --
> rxe_port_up
In this commit, in rxe_net_add, the port->attr.state is set to
IB_PORT_ACTIVE.
But then in the function rxe_init_port_param, port->attr.state is set to
IB_PORT_DOWN again.
