f05e20101e snmp: remove handling of varbind->prev because it is never used 
No code in snmp traverses varbinds backwards so prev is never used.
This also fixes false positive dangling pointer detection by GCC.

7b946fa9b1 SNMP agent rewrite 
- SNMPv2c support
  - Greatly reduced RAM usage, no memory pools any more
  - API cleanup
  - MIB2 is separated from SNMP stack
  - Support for multiple MIBs (snmp_set_mibs call) - e.g. for private MIB
  - Improved MIB2 implementation (tcpConnTable etc.)
  - Redesigned simple and generic API for MIB implementation
  - Comfortable node types for scalar arrays and tables
  - Counter64, bit and truthvalue datatype support
  - Callbacks for SNMP writes
  - Runs on two APIs: RAW and netconn
  - Async API is gone - the stack now supports netconn API instead,
    so blocking operations can be done in MIB calls.
    SNMP runs in a worker thread when netconn API is used.
  - Simplified thread sync support for MIBs - useful when MIBs
    need to access variables shared with other threads without locking
    (used in MIB2 to access lwIP stats from lwIP thread)

Currently in work:
  - Traps rewrite
  - MIB compiler
