The amt.sh requires smcrouted for multicasting routing.
So, it starts smcrouted before forwarding tests.
It must be stopped after all tests, but it isn't.

To fix this issue, it kills smcrouted in the cleanup logic.

Fixes: c08e8baea78e ("selftests: add amt interface selftest script")
Signed-off-by: Taehee Yoo <ap420073@gmail.com>

The v1 patch is here:
https://lore.kernel.org/netdev/20240508040643.229383-1-ap420073@gmail.com/

v2
 - Headline change.
 - Kill smcrouted process only if amt.pid exists.
 - Do not remove the return value.
 - Remove timeout logic because it was already fixed by following commit
   4c639b6a7b9d ("selftests: net: move amt to socat for better compatibility")
 - Fix shebang.

Hi.

I think that the change above is not related to the fix below.
I think it should be in a separate patch targeted at net-next.
And as net-next is currently closed it should be posted once it
reopens, after the 27th May.

The changes below look good to me.
I suggest resending only those changes, targeted at net, as v3.

Thanks.

Okay, I will send a v3 patch that will not change the shebang.
