Before this patch, the blocktime context can be created very early, because postcopy_ram_supported_by_host() <- migrate_caps_check() can happen during migration object init. The trick here is the blocktime context needs system vCPU information, which seems to be possible to change after that point. I didn't verify it, but it doesn't sound right. Now move it out and initialize the context only when postcopy listen starts. That is already during a migration so it should be guaranteed the vCPU topology can never change on both sides. While at it, assert that the ctx isn't created instead this time; the old "if" trick isn't needed when we're sure it will only happen once now.
