Matthew Wilcox (Oracle) 6a6ce20657 9p: Add a migrate_folio method ...

commit 03ddd7725ed1b39cf9251e1a420559f25dac49b3 upstream.

The migration code used to be able to migrate dirty 9p folios by writing
them back using writepage.  When the writepage method was removed,
we neglected to add a migrate_folio method, which means that dirty 9p
folios have been unmovable ever since.  This reduced our success at
defragmenting memory on machines which use 9p heavily.

Fixes: 80105ed2fd (9p: Use netfslib read/write_iter)
