[PATCH 0/1] MR6561: win32u: Don't release surface before passing to create_offscreen_window_surface()

[Jinoh Kang (＠iamahuman)]

create_offscreen_window_surface() expects to borrow a reference from
*window_surface argument if it is not NULL.

Fixes: 8dd4b62e4c7 (win32u: Move offscreen window surface creation fallback., 2024-06-27)
