Currently in driver doing memory allocation for tx_monitor,
tcl_cmd_ring and tcl_status ring. Here driver support for
tx_monitor mode is not there and memory for tcl_cmd and tcl_status
rings are allocated by firmware and it uses that memory instead of
host allocated. So avoid these unused ring setup configuration.

2.34.1
Currently in ath12k_dp_tx_htt_monitor_mode_ring_config()
ath12k_dp_tx_htt_tx_monitor_mode_ring_config() function wrongly called twice.
Fix that by calling ath12k_dp_tx_htt_rx_monitor_mode_ring_config().
Currently monitor mode is disabled in driver so the change is compile
tested and boot sequence verified.

Currently memory allocation for multiple hardware rings done
in host as these memory will be used by firmware/hardware.
But in case of tcl_cmd_ring and tcl_status_ring neither firmware
nor hardware uses host allocated memory and it uses memory
allocated by firmware itself. So avoid tcl_cmd_ring and
tcl_status_ring setup in host.
