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.
