BUG/MEDIUM: list: fix incorrect pointer unlocking in LIST_DEL_LOCKED()

Injecting on a saturated listener started to exhibit some deadlocks
again between LIST_POP_LOCKED() and LIST_DEL_LOCKED(). Olivier found
it was due to a leftover from a previous debugging session. This patch
fixes it.

This will have to be backported if the other LIST_*_LOCKED() patches
are backported.
