minor issue with tautological if statement in grpc client

[jmazzitelli]

I noticed this "tautological" if statement.... basically, it is doing if nil == nil because err is nil at this point:

https://github.com/kiali/kiali/blob/v1.84.0/tracing/jaeger/grpc_client.go#L38

This if-statement should be removed, unless I'm not understanding something in this code.

+1, that if can be removed.

will wait for #7353 to get merged since this will conflict with the same code.
