Juraj Marcin 468a7effde migration: Refactor all incoming cleanup info migration_incoming_destroy() 
Currently, there are two functions that are responsible for calling the
cleanup of the incoming migration state. With successful precopy, it's
the incoming migration coroutine, and with successful postcopy it's the
postcopy listen thread. However, if postcopy fails during in the device
load, both functions will try to do the cleanup.

This patch refactors all cleanup that needs to be done on the incoming
side into a common function and defines a clear boundary, who is
responsible for the cleanup. The incoming migration coroutine is
responsible for calling the cleanup function, unless the listen thread
has been started, in which case the postcopy listen thread runs the
incoming migration cleanup in its BH.
