[PATCH net-next] mctp: Fix warnings reported by clang-analyzer

[Matt Johnston <matt@codeconstruct.com.au>]

net/mctp/device.c:140:11: warning: Assigned value is garbage or undefined
[clang-analyzer-core.uninitialized.Assign]
        mcb->idx = idx;

- Not a real problem due to how the callback runs, fix the warning.

net/mctp/route.c:458:4: warning: Value stored to 'msk' is never read
[clang-analyzer-deadcode.DeadStores]
        msk = container_of(key->sk, struct mctp_sock, sk);

- 'msk' dead assignment can be removed here.
