If clear FDIR rules fail, the error code was logged, but the error code
was useless because it was the sum of all fail code.

This patch fixes it by log the success cnt and fail cnt.

Fixes: fcba820d9b9e ("net/hns3: support flow director")
Fixes: 8eed8acc812e ("net/hns3: add error code to some logs")
