Summary: Proxy agent segmentation fault (NULL pointer dereferenced)

Initial Comment:
A proxy agent will get a segmentation fault when 
handling requests for a subagent after the subagent is 
restarted.  This was found during testing in which the 
proxy agent is using authenticated/encrypted SNMPv3 
to communicate with the subagent.

This occurs because of a dereferenced NULL pointer in 
proxy.c:proxy_got_response().  The provided patch 
ensures that the pointer is evaluated properly.

This patch was tested under the following environment: 
uname -a 
Linux linux-rontabor.togabi.com 2.4.18-3 #1 Thu Apr 18 
07:32:41 EDT 2002 i686 unknown 

NET-SNMP version: 5.0.8

p.s.  If the-powers-that-be find this patch worthy, 
perhaps they wouldn't mind taking a look at patch 
#695192, or even (though certainly less critical) #702711.
