Bryan Boreham b9eab6e4b8 tsdb: simplify internal series delete function (#13261 ) Lifting an optimisation from Agent code, `seriesHashmap.del` can use the unique series reference, doesn't need to check Labels. Also streamline the logic for deleting from `unique` and `conflicts` maps, and add some comments to help the next person. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>		2 years ago
