[PATCH 01/10] rust: pin-init: examples: mark as `#[inline]` all `From::from()`s for `Error`

[Gary Guo]

From: Alistair Francis <alistair.francis@xxxxxxx>

There was a recent request in kernel [1] to mark as `#[inline]` the
simple `From::from()` functions implemented for `Error`.

Thus mark all of the existing

    impl From<...> for Error {
        fn from(err: ...) -> Self {
            ...
        }
    }

functions as `#[inline]`.

While in pin-init crate the relevant code is just examples, it
nevertheless does not hurt to use good practice for them.
