 Currently, if I want to filter 'pre_user_login' and return a WP Error --
 blocking people from using certain usernames or characters, there is no
 check for this and it returns the empty_user_login error instead.

 This patch adds a quick check to $user_login variable to see if it is a
 WP-Error after applying the 'pre_user_login' filter, it returns the error
 instead of continuing processing the function.

 P.S. Apologies if I missed something in this patch/enhancement request. It
 is my first time adding a patch.
