net/ice: cleanup for vec path check

  Move the conditional compilation block to the inner check helper, so we
can reduce the number of multiple ifdef check pairs used.

The build is still failing for arm, some defines like 'RTE_CPUFLAG_AVX2' &
'RTE_CPUFLAG_AVX512F' or functions 'ice_rxq_vec_setup', 'ice_recv_pkts_vec',
'ice_recv_scattered_pkts_vec' etc only defined for x86

It looks like more work is required, to created dummy versions of these failin
functions also moving 'ice_rx_vec_dev_check()' form 'ice_rxtx_vec_sse.c' to
'ice_rxtx.c', otherwise we are having chicken-egg problem. So needs something
similar to done in i40e.

If it is too much work for rc1, we can with existing #ifdef for now, up to you.
