Revert "net/iavf: fix tunnel TSO path selection"

This reverts commit:
3eb4ad8 ("net/iavf: fix tunnel TSO path selection")

This commit was added as part of v21.11.5 and is being removed
for v21.11.6.

This added unneccessary RTE_ETH_TX_OFFLOAD_*_TNL_TSO flags
to IAVF_TX_NO_VECTOR_FLAGS. In cases where those flags are present
but existing ones were not, it may lead to AVX512 tx path
not being selected.

If this combination of items means that AVX512 is not selected
and it is required, then it is better to use v21.11.4,
wait for v21.11.6 or take this revert in you local source.
