xfstests: xfsdump/restore test for partial_reg: Out of records. Extend attrs applied early

Multi-stream xfsdump/xfsrestore of more than partialmax wholly-sparse
files segfaults with the following warning:

  "partial_reg: Out of records. Extend attrs applied early."

Add a test that dumps and restores partialmax + 1 wholly-sparse files.
