Compiler error when using --fix on clippy::implicit_saturating_sub

[FreezyLemon]

Summary

cargo clippy --fix seems to sometimes cause a compiler error when fixing the implicit_saturating_sub lint.

Reproducer

I tried running cargo +nightly clippy --fix on this code:

pub fn test(a: usize, b: usize, c: bool) -> usize {
    if c {
        123
    } else if a >= b {
        0
    } else {
        b - a
    }
}

I expected to see this happen:

pub fn test(a: usize, b: usize, c: bool) -> usize {
    if c {
        123
    } else {
        b.saturating_sub(a)
    }
}

Instead, this happened (compiler error):

pub fn test(a: usize, b: usize, c: bool) -> usize {
    if c {
        17
    } else b.saturating_sub(a)
}

Note to future contributos: This is not an ICE, this is a lint that outputs code that is invalid.
I'll go check this out.
