irqchip/gic-v3: Always trust the managed affinity provided by the core code 

From: Marc Zyngier <maz@kernel.org>

commit 3f893a5962 upstream.

Now that the core code has been fixed to always give us an affinity
that only includes online CPUs, directly use this affinity when
computing a target CPU.
