Subject: [PATCH v3 06/35] x86/apic: Replace pointless apic::dest_logical usage

From: Thomas Gleixner <tglx@...utronix.de>

All these functions are only used for logical destination mode. So reading
the destination mode mask from the apic structure is a pointless
exercise. Just hand in the proper constant: APIC_DEST_LOGICAL.
