The failover_in_progress flag is used to decide the return value of bdev_nvme_failover(). bdev_nvme_delete() calls bdev_nvme_failover() with remove=true to remove nvme_ctrlr->active_path_id. However bdev_nvme_failover() returns zero if nvme_ctrlr->failover_in_progress is true. bdev_nvme_failover() may return zero even if it does not remove nvme_ctrlr->active_path_id. The following will be better. bdev_nvme_failover() returns -EBUSY if nvme_ctrlr->resetting is true, and the caller repeats calling bdev_nvme_failover() until the target trid becomes alternative path or bdev_nvme_failover() returns zero. To do that, the failover_in_progress flag is not necessary any more. Removing the failover_in_progress will also simplify the following patches to unify ctrlr reset and failover.
