SNMP: Do not send responses that we fail to encode (#2151)

When snmp_build() fails, its output buffer must not be used:

    Syscall param sendto() points to uninitialised byte(s)
        by xsendto() (socket.h:118)
        by comm_udp_sendto() (comm.cc:923)
        by snmpConstructReponse() (snmp_core.cc:449)

Also inform the admin about SNMP encoding failures.
