rust: prelude: add `error::code::*` constant items
It is convenient to have all the `Error` constant items (such as `EINVAL`) available as-is everywhere (i.e. for code using the kernel prelude such as kernel modules). Therefore, add all of them to the prelude. For instance, this allows to write `Err(EINVAL)` to create a kernel `Result`: fn f() -> Result<...> { ... Err(EINVAL) } Signed-off-by: Wedson Almeida Filho <wedsonaf@gmail.com> Reviewed-by: Gary Guo <gary@garyguo.net> [Reworded, adapted for upstream and applied latest changes] Signed-off-by: Miguel Ojeda <ojeda@kernel.org>
