[PATCH RFC 06/12] RDMA/rxe: Remove deliver net device event

[Junxian Huang]

From: Yuyu Li <liyuyu6@xxxxxxxxxx>

Since the netdev events of link status is now handled in ib_core,
remove the related code in drivers.

In addition, remove the setting of port->attr.state in rxe_port_up()
and rxe_port_down(), as it is only used in rxe_query_port(), and it
can be replaced by ib_get_curr_port_state().
