net: hns3: keep flow director state unchanged when reset
In orginal codes, driver always enables flow director when
intializing. When user disable flow director with command
ethtool -K, the flow director will be enabled again after
resetting.
This patch fixes it by only enabling it when first initialzing.
Fixes: 6871af29b3ab ("net: hns3: Add reset handle for flow director")
