When delete_ref is called on a symref then it locks its target and then either deletes the target or the symref, depending on whether the flag REF_NODEREF was set in the parameter delopt. Instead, simply pass the flag to lock_ref_sha1_basic, which will then either lock the target or the symref, and delete the locked ref. This reimplements part of eca35a25 (Fix git branch -m for symrefs.).
