Reorder precondition checker

Reorder precondition checker

- Issue:
Some unit tests are failed.

- Solution:
The reason why the tests are failed is because the order for checking
precondition is changed from previous code. All APIs first check
parameters and then check state. However, some function check state
first and the parameters after next patch.

This patch revert the order of precondition check, so every APIs check
precondition with same way.
