Verify extended attributes are not lost after multi-stream
xfsdump/xfsrestore of wholly-sparse files. xfsrestore did not
recognize that if the LAST header was reached with no restoredsz set,
(i.e the LAST header is the only header), the following warning is
displayed:
"partial_reg: Out of records. Extend attrs applied early."
and the extended attributes on the current and following restored
files are lost.

V2:
Updated test description and comments
Changed test status to default to failure
Added missing _requires_XXXX statements
Removed the attr root (-R) namespace argument
