Controller reset ans subsystem shutdown are handled very much the same in the current code, but some of the steps should be different in these two cases. Introduce two new functions, nvme_reset_ctrl() and nvme_shutdown_ctrl(), to separate some portions of the code from nvme_clear_ctrl(). The steps that are made different between reset and shutdown are that BAR.CC is not reset to zero upon the shutdown and namespace data is flushed to backing storage as a part of shutdown handling, but not upon reset.
