octeontx-af: fix hardware timestamp configuration

MAC block on CN10K (RPM) supports hardware timestamp configuration. The
previous patch which added timestamp configuration support has a bug.
Though the netdev driver requests to disable timestamp configuration,
the driver is always enabling it.

This patch fixes the same.
