mctp: mctp-i2c.service: remove existing MCTP EID
Some device may lost its MCTP EID and become unreachable when host
power is off. As a short term solution, we need to restart mctp-i2c
service to setup MCTP endpoint again after host power is on.
Here we need to remove the existing MCTP EID as they may become
outdated.

Don't need as this service isn't used in presubmit platforms.
