migration: Drop unnecessary check in ram's pending_exact()
When the migration frameworks fetches the exact pending sizes, it means this check: remaining_size < s->threshold_size Must have been done already, actually at migration_iteration_run(): if (must_precopy <= s->threshold_size) { qemu_savevm_state_pending_exact(&must_precopy, &can_postcopy); That should be after one round of ram_state_pending_estimate(). It makes the 2nd check meaningless and can be dropped. To say it in another way, when reaching ->state_pending_exact(), we unconditionally sync dirty bits for precopy. Then we can drop migrate_get_current() there too.
