Currently in function extract_peer_stats_count_tlv,
num_peers is copied directly to wmi_host_stats_event
structure without any validation which may cause
out of bound issue if num_peers provided in fixed
param becomes greater than actual number of peer
stats info.
Fix is to validate num_peer_stats_info before populating
stats_param->num_peer_stats_info_ext.
