KVM: Move apic timer migration away from critical section
Migrating the apic timer in the critical section is not very nice, and is absolutely horrible with the real-time port. Move migration to the regular vcpu execution path, triggered by a new bitflag. Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Avi Kivity <avi@qumranet.com>
