rust: error: Add from_result() helper
Add a helper function to easily return C result codes from a Rust function
that calls functions which return a Result<T>.
Lina: Imported from rust-for-linux/rust, originally developed by Wedson
as part of file_operations.rs. Added the allow() flags since there is no
user in the kernel crate yet and fixed a typo in a comment. Replaced the
macro with a function taking a closure, per discussion on the ML.
