hwc: fix use after free when tdm_hwc_set_vblank is enabled

if hwc commit handler is called after vblank handler of
hwc commit is called, data of hwc_commit_handler is used
after it is freed because data of hwc_commit_handler is
freed in vblank handler.

this patch makes data of hwc_commit_handler is not used
to user_data of tdm_hwc_commit when tdm_hwc_set_vblank
is enabled.
