[ Upstream commit e4c2efa1393c6f1fbfabf91d1d83fcb4ae691ccb ]
Correct parameters order in call to ice_tunnel_idx_to_entry function.
Entry in sparse port table is correct when the idx is 0. For idx 1 one correct entry should be skipped, for idx 2 two of them should be skipped etc. Change if condition to be true when idx is 0, which means that previous valid entry of this tunnel type were skipped.
