  netdev-dpdk: Fix flow control configuration.

Currently devices that do not support configuring flow control via the eth_dev
API (e.g. SRIOV VFs) will fail during configuration setup when the interface
is added even if flow control is not requested. This is due to
rte_eth_dev_flow_ctrl_get() being called regardless of whether a flow
control configuration is required.

Fix this by moving the rte_eth_dev_flow_ctrl_get() call to be part of
the control block that avoids configuring flow control when no change
has occurred.
