inp2*.c, cleanup, drop redundant initialisation

which can be dropped to the recently fixed INPgetMod(), see
  inpgmod.c, INPgetMod(), bug fix, missing 'model' assignment

Note:
  there have been INPgetMod() invocations without initialisation,
    causing access to non-initialised memory with the unfixed INPgetMod()
