Subject: [PATCH] io_uring: remove extra argument for overflow flush
Git-commit: 90f67366cb8871951399fb5bcf182e902b896615
Patch-mainline: v5.15-rc1
References: bsc#1199011

Unlike __io_cqring_overflow_flush(), nobody does forced flushing with
io_cqring_overflow_flush(), so removed the argument from it.
