commit 602e57c9799c19f27e440639deed3ec45cfe1651 upstream.
Commit e7d65803e2bb ("nvme-multipath: revalidate paths during rescan") introduced the NVME_NS_READY flag, which nvme_path_is_disabled() uses to check if a path can be used or not. We also need to set this flag for devices that fail the ZNS feature validation and which are available through passthrough devices only to that they can be used in multipathing setups.
