i40evf: allocate virtchnl commands buffer per VF
Currently, i40evf PMD uses a global static buffer to send virtchnl commands to host driver. It is shared by multiple VFs. This patch changed to allocate a virtchnl cmd buffer for each VF. Signed-off-by: Jingjing Wu <jingjing.wu@intel.com> Acked-by: Helin Zhang <helin.zhang@intel.com>
