[PATCH AUTOSEL 6.14 16/30] loop: aio inherit the ioprio of original request

[Sasha Levin <sashal@kernel.org>]

From: Yunlong Xing <yunlong.xing@unisoc.com>

[ Upstream commit 1fdb8188c3d505452b40cdb365b1bb32be533a8e ]

Set cmd->iocb.ki_ioprio to the ioprio of loop device's request.
The purpose is to inherit the original request ioprio in the aio
flow.
