Li Zhijian 0b5bf4ea76 migration: Fix transition to COLO state from precopy 
Commit 4881411136 ("migration: Always set DEVICE state") set a new DEVICE
state before completed during migration, which broke the original transition
to COLO. The migration flow for precopy has changed to:
active -> pre-switchover -> device -> completed.

This patch updates the transition state to ensure that the Pre-COLO
state corresponds to DEVICE state correctly.
