Matthew Wilcox (Oracle) 03ddd7725e 9p: Add a migrate_folio method

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)
