net: hns3: don't restore rules when flow director is disabled 

When user disables flow director, all the rules will be disabled. But
when reset happens, it will restore all the rules again. It's not
reasonable. This patch fixes it by add flow director status check before
restore fules.

Fixes: c17852a893 ("net: hns3: Add support for enable/disable flow director")
