drm/i915: 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@
identifier M;
expression E;
@@
- struct drm_display_mode M = E;
+ struct drm_display_mode M;
@@
identifier decl.M;
expression decl.E;
statement S, S1;

struct drm_display_mode M;
... when != S
+ drm_mode_init(&M, &E);
