title: How to display validation errors on WooCommerce user registration before default errors
body: <p>I'm using the following filter &amp; action to produce some custom validation errors on woocommerce registration process. </p>
  
  <p>filter</p>
  
  <pre><code>woocommerce_registration_errors
  </code></pre>
  
  <p>action</p>
  
  <pre><code>woocommerce_register_post
  </code></pre>
  
  <p>The problem is that both of the hooks above, are fired after some basic validations of woocommerce such as checking email, and password.</p>
  
  <p>I want to limit some IP's to not register, and the error should be at the top of validation errors. So first we check if the ip is valid, now we can go further and do other validations.</p>
  
  <p>I couldn't find any other action or filter.</p>
