zfs: fix sa_modify_attrs handling of variable-sized attributes

- skip length_idx index for a replaced variable-sized attribute
- skip length_idx index for a removed variable-sized attribute
- also re-arranged code to make sure that length_idx is always
  incremented for variable-sized attributes
- additionally add an assertion that the number of actually produced
  attributes is the same as the expected number of resulting
  attributes
