When device is missing its not necessary that btrfs_device::name is null
or the path is different when it reappears. Its possible that device can
go missing after its been scanned where neither of
btrfs_device::name == NULL OR btrfs_device::name != reappear_dev_path,
is true. So just check for btrfs_device::dev_state.missing. Thanks.
