fix: panic with normal errors in Rust

[satoren]

Returns an error when an error can be returned

Did you actually hit this? If so then under which condition?
This is the kind of error that we indeed do not expect unless I missed something.

It is defined as a RequestError. Seems to be returning it except here. The type is also Result<ConsumerStats, RequestError>.

Line 46 in d534be0

pub enum RequestError {

IIRC ConsumerGetStatsRequest never errors, it is just ignored if consumer doesn't exist. No strong opinion though.

Sure, I don't think it will ever happen, but it doesn't hurt either

I have encountered the L1042 panic, but I don't know up to the exact cause because there is no other information available.

Maybe it is an error that the "Channel already closed".
