The final argument to restore should be a destination directory not a device
(as Donald sitting nearby mentioned to me :).

xfsrestore just uses standard posix calls for the most part to
restore the files (seeks, writes, etc...) to a mounted filesystem -
and in many circumstances can restore on a non-xfs mounted filesystem.
It is _NOT_ a low level file system restorer to an unmounted filesystem
like some other restorers.
