BUG/MINOR: lua: initialize the correct idle conn lists for the SSL sockets

Commit 40a007cf2 ("MEDIUM: threads/server: Make connection list
(priv/idle/safe) thread-safe") made a copy-paste error when initializing
the Lua sockets, as the TCP one was initialized twice. Fortunately it has
no impact because the pointers are set to NULL after a memset(0) and are
not changed in between.

This must be backported to 1.9 and 1.8.
