qcacmn: Packet stat collection failure

Browse Source 
Change made I7fd67b02c3b7cb4f1bfe7c6f4641f6d881e25abd
to fix possible NULL dereference of pkt_stats_dump
caused pkt stats collection to fail as pkt_stats_dump
is NULL from cds_pkt_stats_to_logger_thread.

Move NULL check for pkt_stats_dump to just before
it is dereferenced
