dlpar_configure_connector() has two problems in its handling of
ibm,configure-connector's return status:
1. When the status is -2 (busy, call again), we call
ibm,configure-connector again immediately without checking whether
to schedule, which can result in monopolizing the CPU.
2. Extended delay status (9900..9905) goes completely unhandled,
causing the configuration to unnecessarily terminate.
