commitd397d7246cupstream. This test extends "delete and re-add" to validate the previous commit: when the endpoint linked to the initial subflow (ID 0) is re-added multiple times, it was no longer being used, because the internal linked counters are not decremented for this special endpoint: it is not an additional endpoint. Here, the "del/add id 0" steps are done 3 times to unsure this case is validated. The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it validates the previous fix for an issue introduced by this commit ID.
