Subject: x86/msi: Remove pointless vcpu_affinity callback
Git-commit: 9d55f02ad4e8bc67439ff6f8508e2275c3c5d41c
Patch-mainline: v5.10-rc1
References: jsc#SLE-16823

Setting the irq_set_vcpu_affinity() callback to
irq_chip_set_vcpu_affinity_parent() is a pointless exercise because the
function which utilizes it searchs the domain hierarchy to find a parent
domain which has such a callback.

Remove the useless indirection.
