qcacld-3.0: Properly export ol_tx_queue.c APIs

We want to enable the compiler's -Wmissing-prototypes switch, but
there is existing code in ol_tx_queue.c which is generating warnings
because not all public APIs have prototypes defined. Define the
missing prototypes for:
	ol_txrx_vdev_flush()
	ol_txrx_vdev_pause()
	ol_txrx_vdev_unpause()
	ol_tx_throttle_set_level()
	ol_tx_throttle_init_period()

In addition make the following private since they are now only called
internally to ol_tx_queue.c:
	ol_tx_pdev_peer_bal_timer()
	ol_tx_queue_log_alloc()
	ol_tx_queue_display()
