net: ethernet: renesas: rswitch: Fix endless loop in error paths
Coverity reported that the error path in rswitch_gwca_queue_alloc_skb() has an issue to cause endless loop. So, fix the issue by changing variables' types from u32 to int. After changed the types, rswitch_tx_free() should use rswitch_get_num_cur_queues() to calculate number of current queues.
