Subject: [PATCH 5.4 20/28] nvme-loop: clear NVME_LOOP_Q_LIVE when nvme_loop_configure_admin_queue() fails

From: Hannes Reinecke <hare@...e.de>

[ Upstream commit 1c5f8e882a05de5c011e8c3fbeceb0d1c590eb53 ]

When the call to nvme_enable_ctrl() in nvme_loop_configure_admin_queue()
fails the NVME_LOOP_Q_LIVE flag is not cleared.
