ath10k_wmi_tlv_op_pull_peer_stats_info() could try to unlock RCU lock
winthout locking it first when peer reason doesn't match the valid
cases for this function.

Add a default case to return without unlocking.

Fixes: 09078368d516 ("ath10k: hold RCU lock when calling ieee80211_find_sta_by_ifaddr()")
