Subject: x86/apic/uv: Fix inconsistent destination mode
Git-commit: 93b7a3d6a1f0f159d390959de7a1b9ad863d6b26
Patch-mainline: v5.11-rc1
References: jsc#SLE-16823
The UV x2apic is strictly using physical destination mode, but
apic::dest_logical is initialized with APIC_DEST_LOGICAL.
This does not matter much because UV does not use any of the generic
functions which use apic::dest_logical, but is still inconsistent.
