[PATCH 01/11] io-wq: fix worker counting after worker received exit signal

[Hao Xu <hao.xu@linux.dev>]

From: Hao Xu <howeyxu@tencent.com>

acct->nr_workers should be decremented when we break the loop in
io_wq_worker().

Fixes: 78f8876c2d9f ("io-wq: exclusively gate signal based exit on get_signal() return")
