yamt 8af42d8d3c ensure that vnodes with dirty pages are always on syncer's queue. 
- genfs_putpages: wait for i/o completion of PG_RELEASED/PG_PAGEOUT pages by
  setting "wasclean" false when encountering them.
  suggested by Stephan Uphoff in PR/24596 (1).

- genfs_putpages: write protect pages when cleaning out, if
  we're going to take the vnode off the syncer's queue.
  uvm_fault: don't write-map pages unless its vnode is already on
  the syncer's queue.

  fix PR/24596 (3) but in the different way from the suggested fix.
  (to keep our current behaviour, ie. not to require explicit msync.
  discussed on tech-kern@.)

- genfs_putpages: don't mistakenly take a vnode off the queue
  by introducing a generation number in genfs_node.
  genfs_getpages: increment the generation number.
  suggested by Stephan Uphoff in PR/24596 (2).

- add some assertions.
