qcacld-3.0: Fix QCA_LL_PDEV_TX_FLOW_CONTROL invalid memory access

Add QCA_LL_PDEV_TX_FLOW_CONTROL for both
QCA_LL_LEGACY_TX_FLOW_CONTROL and QCA_LL_TX_FLOW_CONTROL_V2
disabled platform, avoid frame drop in driver which leads to bad TCP
TX throughput. Change NUM_TX_QUEUES to 5 for this case to avoid invalid
memory access in wlan_hdd_netif_queue_control().
