drm/vboxvideo: use managed pci functions
Allows us to drop the cleanup code on the floor. Sam noticed in his review: > With this change we avoid calling pci_disable_device() > twise in case vbox_mm_init() fails. > Once in vbox_hw_fini() and once in the error path. v2: Include Sam's review remarks v3: Fix typo in commit summary (Thomas Zimmermann) Acked-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Hans de Goede <hdegoede@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200415074034.175360-6-daniel.vetter@ffwll.ch
