flasher: remove unused ffs_index

ffs_index was used to ensure we updated the ffs header with the actual
size. However, the ffs_index was hardcoded to -1 nd never updated, so
this cade was never executed.

Secondly, recent discussion[1] on the open-power bug tracker suggests that
this was never something that should be done.
