tm: warnings and avp param init. fixes

- wrong pointer was passed to pv_get_avp_name(): int instead of
  unsigned short ( => not the whole int was set and problems on
  big endian archs).
- unneeded pointer casts removed
- variables declared at the function start (otherwise older
  compilers won't work)
