net: ena: Change WARN_ON expression in ena_del_napi_in_range()
The ena_del_napi_in_range() function unregisters the napi handler for rings in a given range. This function had the following WARN_ON macro: WARN_ON(ENA_IS_XDP_INDEX(adapter, i) && adapter->ena_napi[i].xdp_ring); This macro prints the call stack if the expression inside of it is true [1], but the expression inside of it is the wanted situation. The expression checks whether the ring has an XDP queue and its index corresponds to a XDP one. This patch changes the expression to !ENA_IS_XDP_INDEX(adapter, i) && adapter->ena_napi[i].xdp_ring which indicates an unwanted situation. Also, change the structure of the function. The napi handler is unregistered for all rings, and so there's no need to check whether the index is an XDP index or not. By removing this check the code becomes much more readable.
