Subject: rust: pin-init: rename `zeroed` to `init_zeroed`

The name `zeroed` is a much better fit for a function that returns the
type by-value.

Link: https://github.com/Rust-for-Linux/pin-init/pull/56/commits/7dbe38682c9725405bab91dcabe9c4d8893d2f5e
[ also rename uses in `rust/kernel/init.rs` - Benno]
Link: https://lore.kernel.org/all/20250523145125.523275-2-lossin@kernel.org
[ Fix wrong replacement of `mem::zeroed` in the definition of `trait
  Zeroable`. - Benno ]
[ Also change occurrences of `zeroed` in `configfs.rs` - Benno ]
