drm: Use drm_mode_init() for on-stack modes
Initialize on-stack modes with drm_mode_init() to guarantee
no stack garbage in the list head, or that we aren't copying
over another mode's list head.
Based on the following cocci script, with manual fixups:
@decl@

expression E;

- struct drm_display_mode M = E;
+ struct drm_display_mode M;

identifier decl.M;
