afs: Fix waiting for writeback then skipping folio
Commit acc8d8588cb7 converted afs_writepages_region() to write back a folio batch. The function waits for writeback to a folio, but then proceeds to the rest of the batch without trying to write that folio again. This patch fixes has it attempt to write the folio again. [DH: Also remove an 'else' that adding a goto makes redundant] Fixes: acc8d8588cb7 ("afs: convert afs_writepages_region() to use filemap_get_folios_tag()") Signed-off-by: Vishal Moola (Oracle) <vishal.moola@gmail.com> Signed-off-by: David Howells <dhowells@redhat.com> cc: Marc Dionne <marc.dionne@auristor.com> cc: linux-afs@lists.infradead.org Link: https://lore.kernel.org/r/20230607204120.89416-2-vishal.moola@gmail.com/
