The structure was moved to the efivarfs internals in commit2d82e6227e("efi: vars: Move efivar caching layer into efivarfs") after previously being used as the data ABI for efivars until its removal in commit0f5b2c69a4("efi: vars: Remove deprecated 'efivars' sysfs interface"). As efivarfs only uses the structure for the variable name caching layer, the data-related members were never in use. Remove them to avoid implying that efivarfs is bound by the same restrictions that efivars once had. While at it, remove the packed attribute, since we no longer have to guarantee a stable layout.
