Subject: [PATCH 5.10 074/137] io_uring: use better types for cflags

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

[ Upstream commit 8c3f9cd1603d0e4af6c50ebc6d974ab7bdd03cf4 ]

__io_cqring_fill_event() takes cflags as long to squeeze it into u32 in
an CQE, awhile all users pass int or unsigned. Replace it with unsigned
int and store it as u32 in struct io_completion to match CQE.
