Akihiko Odaki e251b58763 ui/gtk: Remove NULL checks in gd_switch 
c821a58ee7 ("ui/console: Pass placeholder surface to display")
eliminated the possibility that NULL is passed as surface to
dpy_gfx_switch and removed some NULL checks from gd_switch, but the
removal was not thoroughly. Remaining NULL checks were confusing for
Coverity and probably also for humans. This change removes those NULL
checks.

/* The QEMU code relies on the assumption that it's always run in

* operations that produce different results depending on the
* locale, such as printf's formatting of decimal numbers, and
* possibly others.
*
* Since GTK+ calls setlocale() by default -importing the locale
* settings from the environment- we must prevent it from doing so
* using gtk_disable_setlocale().
*
* QEMU's GTK+ UI, however, _does_ have translations for some of
* the menu items. As a trade-off between a functionally correct
* QEMU and a fully internationalized UI we support importing
* LC_MESSAGES from the environment (see the setlocale() call
* earlier in this file). This allows us to display translated
* messages leaving everything else untouched.
