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.
