This function uses devm_kcalloc which will zero-allocate the structure. Thus, prior to any queue being setup by ice_ena_vsi_txq, the q_ctx structure will have a q_handle of 0 and a q_teid of 0. These are potentially valid values. Modify the ice_alloc_lan_q_ctx function to initialize every member of the q_ctx array to have invalid values. Modify ice_dis_vsi_txq to ensure that it assigns q_teid to an invalid value when it assigns q_handle to the invalid value as well. This will allow other code to check whether the queue context is currently valid before operating on it.
