Btrfs-progs: fix btrfs-convert rollback to check ROOT_BACKREF
Btrfs has changed to delete subvolume/snapshot asynchronously, which
means that after umount itself, if we've already deleted 'ext2_saved',
rollback can still be completed.
So this adds a check for ROOT_BACKREF before checking ROOT_ITEM since
ROOT_BACKREF is immediately not in the btree after
ioctl(BTRFS_IOC_SNAP_DESTROY) returns.
