rust: debugfs: remove unsafe blocks from traits impl for Vec

Browse source

The previous implementation used an `unsafe` block to manually cast Vec's
slice to a &[u8] using `core::slice::from_raw_parts`.  Instead, the
implementation can be implemented in safe rust using zerocopy's trait
functions `as_bytes()` and `as_mut_bytes()`, respectively, and making use
of deref coercion to implicitly cast Vec to &[T] as `FromBytes` and
`IntoBytes` automatically are implemented on [T] when they are implemented
on T.
