patch 8.1.1092: setting 'guifont' when maximized resizes the Vim window

Problem:    Setting 'guifont' when maximized resizes the Vim window. When
            'guioptions' contains "k" gvim may open with a tiny window.
Solution:   Avoid un-maximizing when setting 'guifont'. (Yee Cheng Chin,
            closes #3808)
