David Howells 0268792f77 cifs: Fix cifs_write_back_from_locked_folio() 
cifs_write_back_from_locked_folio() should return the number of bytes read,
but returns the result of ->async_writev(), which will be 0 on success.  As
it happens, this doesn't prevent cifs_writepages_region() from working as
it will then examine and ignore the pages that are no longer dirty rather
than just skipping over them.

Fixes: d08089f649 ("cifs: Change the I/O paths to use an iterator rather than a page list")
