ath10k: add accounting for the extended peer statistics

Browse Source 
The 10.4 firmware adds extended peer information to the
firmware's statistics payload. This additional info is
stored as a separate data field and the elements are
stored in their own "peers_extd" list.

These elements can pile up in the same way as the peer
information elements. This is because the
ath10k_wmi_10_4_op_pull_fw_stats() function tries to
pull the same amount (num_peer_stats) for every statistic
data unit.
