net: hns: Free irq when exit from abnormal branch

[ Upstream commit c82bd077e1ba3dd586569c733dc6d3dd4b0e43cd ]

1.In "hns_nic_init_irq", if request irq fail at index i,
  the function return directly without releasing irq resources
  that already requested.

2.In "hns_nic_net_up" after "hns_nic_init_irq",
  if exceptional branch occurs, irqs that already requested
  are not release.
