Subject: vm: fix traversing the list of inactive pages

Previously, the pageout code traversed the hash table chain instead of
the list of inactive pages.  The code merely compiled by accident,
because the `struct page' also has a field called `next' for the hash
table chain.

* vm/vm_pageout.c (vm_pageout_scan): Fix traversing the list of
inactive pages.
