runqueue: Fix deferred task/multiconfig race issuestable/2.2-nut
If there are several multiconfigs in play for example a non-multiconfig with
a task with one hash and then three multiconfigs for the same task, different
architectures but the same hash (different to the non-mc), the three mcs
will be deferred until after the non-mc task but then will all run together
and race against each other.
Change the code to re-enable deferred tasks one at a time. This way, if they do
race, they won't run in parallel against each other.
