fwu: make changes to access version agnostic structure fields

With addition of support for version 2 of the FWU metadata structure,
the metadata information is collected into a version agnostic
structure. Make changes to the FWU functions so that the information
that was earlier obtained by reading the metadata structure is now
obtained through this version agnostic structure.
