Bug with search in users.php when user not found

[bl968]

When you do a search in the user administration script users.php and the user does not exist, When you try to do a new search wordpress gives an error because it seems to think that you are attempting to add a new user. This happens when you use the enter key or click on the search button.

Under view source, it's missing the </form> for the <form id="posts-filter" action="" method="get"> so treats it as an add user request.

Patch attached. Moved the </form> outside of the if statement.

(In [7577]) Move user search </form> to correct position. props Nazgul and bl968. fixes #6462 for trunk
