qtnfmac: drop QTN_TLV_ID_NUM_IFACE_COMB TLV type
Information about interface combinations is now available in a fixed portion of struct qlink_resp_get_mac_info. Use that information to get interface combinations. TLV type QTN_TLV_ID_NUM_IFACE_COMB is not needed anymore and can be dropped. Signed-off-by: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
