This fixes a clang 19 warning:
sys/dev/iavf/iavf_lib.c:514:39: error: comparison of different enumeration types ('enum virtchnl_vsi_type' and 'enum iavf_vsi_type') [-Werror,-Wenum-compare]
514 | if (sc->vf_res->vsi_res[i].vsi_type == IAVF_VSI_SRIOV)
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~
The `vsi_type` field of `struct virtchnl_vsi_resource` is of type `enum
virtchnl_vsi_type`, not `enum iavf_vsi_type`. In this case, we can
seamlessly replace the value with `VIRTCHNL_VSI_SRIOV`, which is
numerically equal to `IAVF_VSI_SRIOV`.
