[PATCH] nvme-pci: not invoke nvme_remove_dead_ctrl when change state fails

There is race between nvme_remove and nvme_reset_work that can lead to io hang. nvme_removenvme_reset_work -> change state to DELETING -> fail to change state to LIVE -> nvme_remove_dead_ctrl

[PATCH] nvme-pci: not invoke nvme_remove_dead_ctrl when change state fails

There is race between nvme_remove and nvme_reset_work that can lead to io hang. nvme_removenvme_reset_work -> change state to DELETING -> fail to change state to LIVE -> nvme_remove_dead_ctrl
