When Wireshark receives an AgentX Ping-PDU that contains a zero length
'context' identifier it emits the following warning:

14:30:20          Warn Dissector bug, protocol AgentX, in packet 1066:
tvbuff.c:2571: failed assertion "bufsize != 0"


The attached patch prevents the warning message from appearing under that
circumstance.  Note:  This patch will also prevent the warning under all other
conditions where a zero length string is specified anywhere in the protocol
dissector.
