Chirantan Ekbote f4d6014c41 data_model: Don't heap allocate in DataInit::from_reader ... We can use MaybeUninit instead of heap allocation to ensure that our buffer has the proper size and alignment. `from_reader` is used for every message in the fs device and this saves us some unnecessary small heap allocations. Switch Reader::read_obj to use this method so that we don't have multiple implementations of the same thing. This also fixes some unsoundness in read_obj where we were creating a `&mut [u8]` out of uninitialized data.
