Blocking firmware update via IPMB

Updated few firmware update commands to return command not available
when they are executed via ipmb

Tested:

Tested the commands using FTF tool(which uses IPMB as the medium)
returns proper error code 0xD5(command not available).

Tested the commands from uefi, BMC terminal and remote commands are
working fine.

Firmware update using fwupdapi.efi is working fine.
