wifi: ath10k: Use list_count_nodes()

ath10k_wmi_fw_stats_num_peers() and ath10k_wmi_fw_stats_num_vdevs() really
look the same as list_count_nodes(), so use the latter instead of hand
writing it.

The first ones use list_for_each_entry() and the other list_for_each(), but
they both count the number of nodes in the list.

Compile tested only.
