irqchip/gic-v3-its: Fix build for !SMP
Commit 835f442fdbce ("irqchip/gic-v3-its: Limit memreserve cpuhp state
lifetime") added a reference to cpus_booted_once_mask, which does not
exist on !SMP builds, breaking the build for such configurations.
Given the intent of the check, short circuit it to always pass.
