Fixes: grpc#8474 The race is in [ReportLoad](https://github.com/grpc/grpc-go/blob/9186ebd774370e3b3232d1b202914ff8fc2c56d6/xds/internal/xdsclient/clientimpl_loadreport.go#L35C2-L44C21) function of clientImpl. The implementation was recently changed as the part of [xds client migration](grpc@082a927). The [comment](https://github.com/grpc/grpc-go/blob/85240a5b02defe7b653ccba66866b4370c982b6a/xds/internal/xdsclient/clientimpl.go#L86C2-L87C16) says that `lrsclient.LRSClient` should be initialized only at creation time but that was not the case. It was being initialized at the time of calling `ReportLoad` function. RELEASE NOTES: - lrsclient: - Fix a race condition where the `LRSClient` was not initialized at creation time but it was being initialized at the time of calling the `ReportLoad` function. - Creating an `LRSClient` no longer requires a node ID.
