The BTRFS_DEV_REPLACE_ITEM_STATE_x series defines as shown in [1] are
unused in both kernel and btrfs-progs.
[1]
btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_FINISHED 2
btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_CANCELED 3
btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_SUSPENDED 4
Further the BTRFS_DEV_REPLACE_ITEM_STATE_x values are different form its
counterpart BTRFS_IOCTL_DEV_REPLACE_STATE_x series as shown in [2].
[2]
btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_SUSPENDED 2
btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_FINISHED 3
btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_CANCELED 4
So this patch deletes the BTRFS_DEV_REPLACE_ITEM_STATE_x altogether,
they're not used by anything.

Systems with older kernels won't have these available, and the copies in
btrfs-progs aren't quite compatible, so for now, let's just copy these
in. We can potentially deduplicate some of this in the future.
