ISSetIdentity: change permanence semantics to match what was before

If you called ISSetIdentity() before, it would set is->isidentity = PETSC_TRUE.
If you called ISIdentity, if is->isidentity was set it would return PETSC_TRUE,
and would only call is->ops->identity if is->isidentity was PETSC_FALSE.
So ISSetIdentity() should have permanence and ISGetIdentity() should have
recomputation
