Subject: media: v4l: vsp1: Remove the unneeded vsp1_video_buffer video field

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

commit e51daefc228aa164adcc17fe8fce0f856ad0a1cc upstream.

The field is assigned but never read, remove it.

This fixes a bug caused by the struct vb2_buffer field not being be the
very first field of the vsp1_video_buffer buffer structure as required
by videobuf2.
