qcacmn: Initialize min_delay of hist_stats to high value

Browse Source 
As the value of min_delay is initialized to 0,
during the updation of min_delay per-packet,the
new value is compared with 0.This results in the
value of min_delay always becoming 0.Fix this by
initializing min_delay to very high value.
