Subject: [PATCH 08/14] NVMe: nvme_dev_map() is a bad place to set admin queue IRQ number

Initialization of the admin queue interrupt number within
nvme_dev_map() is confusing. Just keep nvme_dev_map() and
nvme_dev_unmap() counterparts simple and let deal function
nvme_configure_admin_queue() with the admin queue in full.
