Subject: i40e: Disable hw-tc-offload feature on driver load
Patch-mainline: v5.18-rc1
Git-commit: 647c65e1433220866ab6d3a572c80acedde1a5b4
References: jsc#PED-372

After loading driver hw-tc-offload is enabled by default.
Change the behaviour of driver to disable hw-tc-offload by default as
this is the expected state. Additionally since this impacts ntuple
feature state change the way of checking NETIF_F_HW_TC flag.
