Various improvements to vm_contig_grow_cache().  Most notably, even when
it can't sleep, it can still move clean pages from the inactive queue to
the cache.  Also, when a page is cached, there is no need to restart the
scan.  The "next" page pointer held by vm_contig_launder() is still
valid.  Finally, add a comment summarizing what vm_contig_grow_cache()
does based upon the value of "tries".
