[dpdk-stable] [dpdk-dev] [PATCH] bus/vmbus: fix wrong allocation for device.name

[wangyunjian <wangyunjian@huawei.com>]

From: Yunjian Wang <wangyunjian@huawei.com>

We do not need and should not allocate memory for device.name.
The device.name should be set point to the devargs->name.

Fixes: 831dba47bd36 ("bus/vmbus: add Hyper-V virtual bus support")
