Revert "net-snmp: fix memory leak"

Browse Source 
This reverts commit d0c2a3d383.

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
tclist is always allocated in netsnmp_init_mib_internals, when doing multiple init_snmp("")/snmp_shutdown("") this memory is never free'd.
Upstream-Status: Backport [https://github.com/net-snmp/net-snmp/commit/4bd0d9a8a2860c2c46307aef5ee1ccc69f7e3b62]
