drm/fb-helper: Fix fb refcounting in pan_display_atomic
In commit bbb1e524 Author: Rob Clark <robdclark@gmail.com> Date: Tue Aug 25 15:35:58 2015 -0400 drm/fb-helper: atomic restore_fbdev_mode().. we've forgotten to do the plane->old_fb refcount dance for pan_display_atomic, which can result in refcount leaks if the current configuration is not from fbcon. Which apparently can happen when vt-switching - fbcon does a pan first before a set_par. OCD-align function parameters while at it. v2: Actually git add the OCD.
