[PATCH] pdump: clear statistics when enabled

[Stephen Hemminger <stephen@networkplumber.org>]

The pdump statistics are used to keep track of the number
of packets captured, filtered, etc. These need not be cumalative
and instead should be start counting when capture starts.

This fixes the issue where multiple invocations of dumpcap
would include counts from previous invocations.

Bugzilla ID: 1604
Fixes: 10f726efe26c ("pdump: support pcapng and filtering")
