hw/block/nvme: open code for volatile write cache
Volatile Write Cache(VWC) feature is set in nvme_ns_setup() in the initial time. This feature is related to block device backed, but this feature is controlled in controller level via Set/Get Features command. This patch removed dependency between nvme and nvme-ns to manage the VWC flag value. Also, it open coded the Get Features for VWC to check all namespaces attached to the controller, and if false detected, return directly false.
