Eli Cohen 680ab9d69a vdpa: Protect vdpa reset with cf_mutex ... Call reset using the wrapper function vdpa_reset() to make sure the operation is serialized with cf_mutex. This comes to protect from the following possible scenario: vhost_vdpa_set_status() could call the reset op. Since the call is not protected by cf_mutex, a netlink thread calling vdpa_dev_config_fill could get passed the VIRTIO_CONFIG_S_FEATURES_OK check in vdpa_dev_config_fill() and end up reporting wrong features.
