Subject: [PATCH] io_uring: use unsigned_abs() for isize -> usize

Fixes a new clippy lint:
<https://rust-lang.github.io/rust-clippy/master/index.html#cast_abs_to_unsigned>

We still need the cast to u32, since the other parts of the expression are
u32.

BUG=b:243677117
TEST=tools/clippy # with Rust 1.62
