Revert "net-snmp: fix memory leak"

This reverts commit d0c2a3d3.

Please revert my patch.

After I rebase the latest codes from kirkstone. I found my patch had a bad character. This caused net-snmp do_patch failure.

After some tries, I still failed to resolve this.

The cherry-pick in my side picked copyright change. But after sending the patch via git send-mail, the character changed.

Sorry again.

Thanks.

-Subject: [PATCH] unload_all_mibs: fix memory leak by freeing tclist
