Import the modules used in the crate instead of spelling the fully-qualified paths at every use site, and collapse Result<T, io::Error> into io::Result<T>. This covers the feature-gated modules (fw_cfg, ivshmem, pvmemcontrol) as well, leaving the whole crate free of clippy::absolute_paths warnings.
