Daniel Wagner 4099d8f057 nvme-fc: don't hold rport lock when putting ctrl 
[ Upstream commit b71cbcf7d1 ]

nvme_fc_ctrl_put can acquire the rport lock when freeing the
ctrl object:

nvme_fc_ctrl_put
  nvme_fc_ctrl_free
    spin_lock_irqsave(rport->lock)

Thus we can't hold the rport lock when calling nvme_fc_ctrl_put.

Justin suggested use the safe list iterator variant because
nvme_fc_ctrl_put will also modify the rport->list.
