net/i40e: revert fix FDIR check programming ret error
Checks
Commit Message
This reverts commit 7546dc4a1331340ecb665af9af0a005bb8b657c8.
In i40e FDIR PMD code for checking programming status,
when the action of add FDIR filter is ok, i40e NIC will
not write back to programming status descriptor, so if
PMD code check DD is not done after period of time dealy,
it means the add or remove filter action is ok. It only write
back descriptor when fail. So, there is no issue for the orignal
code.
