snmp_pdu_free the right object at the right time in snmptool_walk

r310892 was on the right track, but unfortunately it was resolving
the problem incorrectly and accidentally leaking memory in the
process.

- Call snmp_pdu_free on req before calling snmp_pdu_create on it
  at the bottom of the outer while loop
- Call snmp_pdu_free on resp after calling snmpwalk_nextpdu_create
  in the inner loop
