[PATCH for xfstests] xfstests: fix to make tests/btrfs/013 really work

[ZhangZhen]

Hi Wang,
Thank you for reviewing my patch.

I ran the test using btrfs progs v0.19(OpenSuse 12.3) previously and got a fail situation.
I verified v3.12 this morning and it work well as you mentioned.

Althouth the new version doesn't have this problem, I think it would be better to fix this.
I'll fix the titile and resend it.
