    DEVFS - Use v_associate_rdev; fix vcount/count_dev
    
    to avoid trouble with both vrevoke() and the drm code which calls
    vm_mmap, which in turn expects a vnode as handle, but drm only has
    a cdev. If associate_rdev is used, the cdev will have a list of
    vnodes currently in use  associated with it.
    
    - This fixes a problem with drm which caused a panic when used.
    
    - count_dev, which is used by vcount, now returns the vnodes'
    opencount instead of the number of references.
