octeon_ep: ensure octep_get_link_status() successfully before octep_link_up()
[ Upstream commit 9d3ff7131877fb092185c369fbb14b57ac4e7cec ]
octep_get_link_status() can fail because send mbox message failed, then
octep_get_link_status() will return ret less than 0. Excute octep_link_up()
as long as ret is not equal to 0 in octep_open() now. That is not correct.
The value type of link.state is enum octep_ctrl_net_state. Positive value
represents up. Excute octep_link_up() when ret is bigger than 0.
