If we could not take the lock, we add an error to the `strbuf err` and return. However, this code is dead. The reason is that we take the lock using `LOCK_DIE_ON_ERROR`. Drop the flag to allow our more gentle error-handling to actually kick in.
We could instead just drop the dead code and die here. But everything is prepared for gently propagating the error, so let's do that instead.
There is similar dead code in `delete_pseudoref()`, but let's save that for the next patch.
While at it, make the lock non-static.
