Keep track of how many pages a vnode hold with vhold and vholdrele
so that we can get back the old behavior where a vnode with cached data
is less likely to be recycled than a vnode without cached data.
XXX - This is a brute-force solution - we do it where uvmexp.vnodepages
are changed, I am not really sure it is correct but people have been
very happy with the diff so far and want this in the tree.
