From: Li Nan <linan122@huawei.com>

In raid10_sync_request(), 'any_working' indicates if any IO will
be submitted. When there's only one In_sync disk with badblocks,
'any_working' might be set to 1 but no IO is submitted. Fix it by
setting 'any_working' after badblock checks.

Fixes: e875ecea266a ("md/raid10 record bad blocks as needed during recovery.")
