nvme: fix the read-only state for zoned namespaces with unsupposed features
commit 2f4c9ba23b88 ("nvme: export zoned namespaces without Zone Append support read-only") marks zoned namespaces without append support read-only. It does iso by setting NVME_NS_FORCE_RO in ns->flags in nvme_update_zone_info and checking for that flag later in nvme_update_disk_info to mark the disk as read-only. But commit 73d90386b559 ("nvme: cleanup zone information initialization") rearranged nvme_update_disk_info to be called before nvme_update_zone_info and thus not marking the disk as read-only. The call order cannot be just reverted because nvme_update_zone_info sets certain queue parameters such as zone_write_granularity that depend on the prior call to nvme_update_disk_info. Remove the call to set_disk_ro in nvme_update_disk_info. and call set_disk_ro after nvme_update_zone_info and nvme_update_disk_info to set the permission for ZNS drives correctly. The same applies to the multipath disk path.
