drm/panic: Fix uninitialized drm_scanout_buffer.set_pixel() crash
No implementations of drm_plane_helper_funcs.get_scanout_buffer() fill
in the optional drm_scanout_buffer.set_pixel() member. Hence the member
may contain non-zero garbage, causing a crash when deferencing it during
drm panic.
Fix this by pre-initializing the drm_scanout_buffer object before
calling drm_plane_helper_funcs.get_scanout_buffer().
Fixes: 24d07f114e4ec760 ("drm/panic: Add a set_pixel() callback to drm_scanout_buffer")
