Set the v_hash for a new vnode in the getnewvnode() to the value
calculated based on the vnode structure address.  Filesystems using
vfs_hash_insert() override the v_hash using the standard formula of
(inode_number + mnt_hashseed).  For other filesystems, the
initialization allows the vfs_hash_index() to provide useful hash too.
