Noralf Trønnes 0586576950 drm/fb-helper: Fix drm_fb_helper_hotplug_event() NULL ptr argument
drm_fb_helper_hotplug_event() should tolerate the fb_helper argument being
NULL. Commit 03a9606e7f ("drm/fb-helper: Avoid race with DRM userspace")
introduced a fb_helper dereference before the NULL check.
Fixup by moving the dereference after the NULL check.
