wlan: Reallocate skb before reusing in wlan_logging pkt_stats filled list

In wlan_queue_pkt_stats_for_app, if the pkt_stat_free_list is empty,
the current node is taken from the head of pkt_stat_filled_list,
detached from the list and skb is set for re-use. This current node
is reattached back to the tail of the pkt_stat_filled_list for the next
log. This could lead to skb tail overrun as skb is not reset before
re-use.

Free the existing skb allocated to the pkt_stat_filled_list head
and allocate again to have a clean skb.
