btrfs-progs: do a separate probe for transient replacing device
As mentioned in the kernel patch btrfs: ioctl BTRFS_IOC_FS_INFO and BTRFS_IOC_DEV_INFO miss-matched with slots The count as returned by BTRFS_IOC_FS_INFO is the number of slots that btrfs-progs would allocate for the BTRFS_IOC_DEV_INFO ioctl. Since BTRFS_IOC_DEV_INFO would loop across the seed devices, So its better ioctl BTRFS_IOC_FS_INFO returns the total_devices instead of num_devices. The above mentioned patch just does that. That is, it returns total_devices instead of num_devices. Which means we need to probe for the replacing device separately. This patch will probe for the replacing device separately.
