[PATCH AUTOSEL 5.7 21/25] io_uring: missed req_init_async() for IOSQE_ASYNC

[Sasha Levin <sashal@kernel.org>]

From: Pavel Begunkov <asml.silence@gmail.com>

[ Upstream commit 3e863ea3bb1a2203ae648eb272db0ce6a1a2072c ]

IOSQE_ASYNC branch of io_queue_sqe() is another place where an
unitialised req->work can be accessed (i.e. prior io_req_init_async()).
Nothing really bad though, it just looses IO_WQ_WORK_CONCURRENT flag.
