[PATCH 3/8] drm/nouveau: Do not set struct drm_driver.lastclose

[Thomas Zimmermann <tzimmermann@suse.de>]

Remove the implementation of struct drm_driver.lastclose. The hook
was only necessary before in-kernel DRM clients existed, but is now
obsolete.

The code within nouveau_vga_lastclose() is performed elsewhere in the
DRM fbdev emulation.
