internal/upload: fix upload locking

The upload locking logic left a brief race that could lead to duplicate
uploads, as the existence of an uploaded report was checked before
locking, not after. Fix this.

As described in golang/go#67737, more races exist that could lead to
broken or partial uploads, but this should prevent overcounting uploads,
as was originally intended.

This closes golang/go#65970, as it is the last thing I feel comfortable
doing relative to the upload process. More refactoring will have to wait
until 1.24.

For golang/go#67737
Fixes golang/go#65970

Go Telemetry

This repository holds the Go Telemetry server code and libraries, used for hosting telemetry.go.dev and instrumenting Go toolchain programs with opt-in telemetry.

Warning: this repository is intended for use only in tools maintained by the Go team, including tools in the Go distribution and auxiliary tools like gopls or govulncheck. There are no compatibility guarantees for any of the packages here: public APIs will change in breaking ways as the telemetry integration is refined.

Notable Packages
