Subject: [PATCH] kmsdrm: Fix wrong check on KMSDRM_CreateWindow.

A previous cleanup commit inverted a statement that checked the return value of
a KMSDRM_CreateSurfaces call during KMSDRM_CreateWindow, which causes the video
backend to always fail despite success.

This commit restores the intended behavior.

Fixes: 3c501b963dd8 ("Clang-Tidy fixes (#6725)").
(cherry picked from commit 0187209f461b84d22fc49a03369506e06448f47f)
