[petsc-dev] Regression in PetIGA with petsc/master

[Hong]

Lisandro :
I fixed bug in branch hzhang/fix-ao2petscis:
https://bitbucket.org/petsc/petsc/commits/260dbea8cadd3eeca7e59945a235ff92ceae1333

I tested "-iga_dof 3" as well.
Let me know if you still encounter problems, or have any comments on this
fix.
