migration: Fix hang after error in destination setup phase

Browse source 
If the destination side fails at migration_ioc_process_incoming()
before starting the coroutine, it will report the error but QEMU will
not exit.

Set the migration state to FAILED and exit the process if
exit-on-error allows.
