[Qemu-devel] [PATCH 01/11] migration: assert colo instead of check

[Peter Xu <peterx@redhat.com>]

When reaching here if we are still "active" it means we must be in colo
state.  Assert it instead of check it in if condition.

Finally I want to use "switch" here rather than lots of complicated if
clauses.
