[PATCH V3 6/8] nvme-core: align fabrics_q teardown with admin_q in nvme_free_ctrl

[Maurizio Lombardi]

Currently, the final reference for the fabrics admin queue (fabrics_q)
is dropped inside nvme_remove_admin_tag_set(). However, the primary
admin queue (admin_q) defers dropping its final reference until
nvme_free_ctrl().

Move the blk_put_queue() call for fabrics_q from nvme_remove_admin_tag_set()
to nvme_free_ctrl(). This aligns the lifecycle management of both admin
queues, ensuring they are freed symmetrically when the controller is finally
torn down.
