net/ipn3ke: remove useless if statement

Coverity complains that this statement is not needed as the goto
label is on the next line anyway. Remove the if statement.

653        ret = ipn3ke_cfg_parse_i40e_pf_ethdev(afu_name, pf_name);
   CID 337930 (#1 of 1): Identical code for different branches
   (IDENTICAL_BRANCHES)identical_branches: The same code is executed
   when the condition ret is true or false, because the code in the
   if-then branch and after the if statement is identical. Should
   the if statement be removed?
654        if (ret)
655                goto end;
   implicit_else: The code from the above if-then branch is identical
   to the code after the if statement.
