[v2,08/11] fuse: convert fuse_writepage_need_send to take a folio

Commit Message

fuse_writepage_need_send is called by fuse_writepages_fill() which
already has a folio.  Change fuse_writepage_need_send() to take a folio
instead, add a helper to check if the folio range is under writeback and
use this, as well as the appropriate folio helpers in the rest of the
function.  Update fuse_writepage_need_send() to pass in the folio
directly.
