After the referenced commit, the incoming side doesn't exit
automatically after a failure. Tests that expect the destination to
fail should use -incoming defer, issue QMP migrate-incoming, wait for
the failure event and issue QMP quit.

Fix the dirty_limit test which wasn't updated properly.

Fixes: 4e8c4dda97 ("tests/qtest/migration: Force exit-on-error=false")
