nvme-rdma: Remove duplicate call to nvme_remove_namespaces
nvme_uninit_ctrl already does that for us. Note that we reordered nvme_rdma_shutdown_ctrl and nvme_uninit_ctrl, this is perfectly fine because we actually want ctrl uninit (aen, scan cancellation and namespaces removal) to happen before we shutdown the rdma resources. Also, centralize the deletion work and the dead controller removal work code duplication into __nvme_rdma_shutdown_ctrl that accepts a shutdown boolean.
