This patch postpones vapic_paddr initialization, which is perfromed
by the migration functions. When vapic_paddr is synchronized within
the migration process, apic_common functions could operate with incorrect
apic state, if it hadn't loaded yet. This patch postpones the synchronization
until whole virtual machine state is loaded.
