[PATCH 14/14] NVMe: Rework "NVMe: Disable admin queue on init failure" commit

[Alexander Gordeev]

This update partially reverts commit c5dc919 ("NVMe: Disable
admin queue on init failure") to roll back easy readable
nvme_free_queues() function. Commit's c5dc919 functionality
aimed to free admin queue IRQ on init failure is preserved.
