rust_binder: use pin_init::zeroed for file_operations initialization

All types in `bindings` implement `Zeroable` if they can. This enables using `pin_init::zeroed()` for `file_operations` initialization instead of relying on `unsafe { core::mem::MaybeUninit::zeroed().assume_init() }`. This change improves readability and removes an unnecessary unsafe block.
