This patch removes the only call to flowtype_to_str not under #if
defined(RTE_NET_I40E) || defined(RTE_NET_IXGBE).

As reported by the CI, it breaks compilation when disabling net/i40e
and net/ixgbe drivers because it results in a static unused symbol
left behind.

Please fix by removing the unnecessary fwd declaration of this symbol,
then moving flowtype_to_str function under the #if
defined(RTE_NET_I40E) || defined(RTE_NET_IXGBE) check.

I marked this patch as changes requested, thanks.
