Preparing the values and letting the caller OR multiple fields together should be preferred over assigning to their arguments. Signed-off-by: Khang D Nguyen <[email protected]>

Currently, mctpd handles Set EID message as a bus owner, which means it assumes it has at least one local EID and rejects all Set Endpoint ID requests. This commit handles the case where mctpd runs on an endpoint and it has no EID set yet. Signed-off-by: Khang D Nguyen <[email protected]>

This change takes a little long for me to push out, mainly because I am not sure how the specification interacts with our MCTP in-kernel infrastructure, where a single EID address can be assigned on multiple interfaces.
I think I mostly know how this maps to the spec now. The spec suggests:
This PR address the endpoint case, where it will accept the EID from every interfaces it is connected to.
Also, this PR also fixes the response for Bus Owner. Instead of rejecting with
0b01 EID assignment rejected, this PR rejects withMCTP_CTRL_CC_ERROR_UNSUPPORTED_CMD. Rejecting EID assignment is reserved for the case where a bridge is rejecting subsequent EID assignments from other bus owners it is connected to.
