[PATCH 05/11] drm/exynos: removed pageflip_event_list init code when closed.

[Inki Dae]

From: Joonyoung Shim <jy0922.shim at samsung.com>

if one process is terminated by ctrl-c while two processes are
using pageflip feature then for last pageflip event,
user can't get poll from kernel side so this patch fixes the problem.
