sched: Switch the fallback task allowed cpumask to HK_TYPE_DOMAIN
Tasks that have all their allowed CPUs offline don't want their affinity
to fallback on either nohz_full CPUs or on domain isolated CPUs. And
since nohz_full implies domain isolation, checking the latter is enough
to verify both.
Therefore exclude domain isolation from fallback task affinity.
