rxkad: silence unused variable warnings in v5gen.c
Sprinkle AFS_UNUSED attributes where the compiler complains
about unused variables.
Note that this file is assembled from code generated by the heimdal
source. A similar fix exists in the generator code upstream, so
when the file is re-generated in the future it should not be
necessary to re-apply this.
