Page info not closing on non-Mac desktop when close button icon clicked.

Page info not closing on non-Mac desktop when close button icon clicked.

This fixes the page info close icon so when it is clicked, it closes the dialog
properly. This was a regression introduced by
https://codereview.chromium.org/473643002/ where the widget's Close() method was
accidentally moved inside of a conditional in the button handler when it really
should have been executed on all button presses. This moves the Close() method
outside the conditional so it properly closes the dialog.
