[PATCH ath-next v2 1/3] wifi: ath12k: Use runtime device count in dp stats display

The REO Rx Received and Rx WBM REL SRC Errors display loops in
ath12k_debugfs_dump_device_dp_stats() iterate up to the compile-time
constant ATH12K_MAX_DEVICES.  This unconditionally prints zeros
in columns with no hardware behind it, making the output misleading.

Replace the compile-time bound with the runtime ab->ag->num_devices so
only live device slots appear in the output.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
