BUG/MEDIUM: lists: Avoid an infinite loop in MT_LIST_TRY_ADDQ().
In MT_LIST_TRY_ADDQ(), deal with the "prev" field of the element before the
"next". If the element is the first in the list, then its next will
already have been locked when we locked list->prev->next, so locking it
again will fail, and we'll start over and over.
This should be backported to 2.3.
