tests/qtest/migration-test: Don't leak QTestState in test_multifd_tcp_cancel()

Browse Source 
In test_multifd_tcp_cancel() we create three QEMU processes: 'from',
'to' and 'to2'.  We clean up (via qtest_quit()) 'from' and 'to2' when
we call test_migrate_end(), but never clean up 'to', which results in
this leak:

Direct leak of 336 byte(s) in 1 object(s) allocated from:

Call qtest_quit() on 'to' to clean it up once it has exited.
