 When using the screen_options_show_screen filter to remove the screen tab
 completely, an undefined variable notice appears with WP_DEBUG on.
 Specifically, the $screen_layout_columns variable is undefined because the
 current code expects it to be set and to be an integer.

 This patch fixes it by setting it equal to itself while still casting it
 as an integer. Can't find any issues in my testing.
