mtc: Clear init magic on chainload

Fixes a hang caused when rebooting 2 payload from L4T with old hekate in vendor partition.

L4T does not overwrite the nyx storage where the Minerva configuration is stored.
This makes new Minerva parse the wrong tables from old hekate and eventually hang the RAM, which causes an exception on BPMP.
