[PATCH 1/3] btrfs-progs: let user know that devid can be used if path is missing

[Anand Jain <anand.jain@oracle.com>]

When the device disappear the path goes missing,
and that will be the one of the reason that user
will replace the device.

The devid of the missing btrfs device can be
obtained using the new cli option
 btrfs fi show --kernel (coming soon)

And which can be used in the replace command.
