ice: don't ignore return codes in VSI related code

Browse source 
There were few smatch warnings reported by Dan:
- ice_vsi_cfg_xdp_txqs can return 0 instead of ret, which is cleaner
- return values in ice_vsi_cfg_def were ignored
- in ice_vsi_rebuild return value was ignored in case rebuild failed,
  it was a never reached code, however, rewrite it for clarity.
- ice_vsi_cfg_tc can return 0 instead of ret

Fixes: 6624e780a5 ("ice: split ice_vsi_setup into smaller functions")
