ath11k: Fix the rx_filter flag setting for peer rssi stats

Set the rx_filter in ath11k_mac_config_mon_status_default(),
only when the rx_filter value exists in ath11k_debug_rx_filter().

Without this change, rx_filter gets set to 0 and peer rssi stats
aren't updating properly from firmware.

Tested-on: IPQ8074 WLAN.HK.2.1.0.1-01230-QCAHKSWPL_SILICONZ-4
