Use `kernel::ffi::c_void` instead of `core::ffi::c_void` for consistency
and to centralize abstraction.

Since `kernel::ffi::c_void` is a straightforward re-export of
`core::ffi::c_void`, both are functionally equivalent. However, using
`kernel::ffi::c_void` improves consistency across the kernel's Rust code
and provides a unified reference point in case the definition ever needs
to change, even if such a change is unlikely.

So in sum, I believe it's reasonable to keep the diff unchanged... but
I'm happy to adjust if you'd prefer a different approach.

Changes in v2:
- Add "Link" tag to the related discussion on Zulip
- Reword the commit message to clarify `kernel::ffi::c_void` is a re-export
- Link to v1: https://lore.kernel.org/rust-for-linux/20250526162429.1114862-1-y.j3ms.n@gmail.com/
