net/ice: fix Tx queue vector setup

Browse Source 
If vector mode is not allowed for Tx, no need to perform vector
related setup for Tx queue.

The patch deferred vector setup for Tx queue to the place that
vector mode is confirmed to be allowed.

Fixes: 28f9002ab67f ("net/ice: add Tx AVX512 offload path")
