Backport commit dad651b2a44e ("nvme-pci: do not set the NUMA node of device if it has none")

Hi,

Please backport commit dad651b2a44e ("nvme-pci: do not set the NUMA node of device if it has none") to stable branches 6.1, 5.15, 5.10, 5.4, 4.19, and 4.14. The commit fixes a4aea5623d4a ("NVMe: Convert to blk-mq") which was introduced in v3.19 but I forgot to add this when sending the patch.
