qapi: introduce exit-on-error parameter for migrate-incoming

Now we do set MIGRATION_FAILED state, but don't give a chance to
orchestrator to query migration state and get the error.

Let's provide a possibility for QMP-based orchestrators to get an error
like with outgoing migration.

For hmp_migrate_incoming(), let's enable the new behavior: HMP is not
and ABI, it's mostly intended to use by developer and it makes sense
not to stop the process.

For x-exit-preconfig, let's keep the old behavior:
 - it's called from init(), so here we want to keep current behavior by
   default
 - it does exit on error by itself as well
So, if we want to change the behavior of x-exit-preconfig, it should be
another patch.
