[PATCH v3] rust: doc: Clean up formatting in io.rs

[Sai Vishnu M <saivishnu725@gmail.com>]

From: Sai Vishnu M <saivishnu725@gmail.com>

Removed reference to internal variables in the comment of `IoMem`
This avoids using private variable names in public documentation.

Reported-by: Miguel Ojeda <ojeda@kernel.org>
Closes:  https://github.com/Rust-for-Linux/linux/issues/1167
