wifi: ath12k: Avoid allocating rx_stats when ext_rx_stats is disabled
Currently, driver allocates the struct ath12k_rx_peer_stats for each
station regardless of whether ext_rx_stats is enabled. This structure
is populated by the monitor destination ring for both single-user and
multi-user scenarios when ext_rx_stats is enabled. However, when
ext_rx_stats is disabled, this allocation is unnecessary and results in
additional memory consumption.
To address this issue, allocate the struct ath12k_rx_peer_stats only when
ext_rx_stats is enabled through debugfs. This change prevents unnecessary
memory allocation. Additionally, ensure that the station dump RSSI is
updated irrespective of the ext_rx_stats enablement.
