[PATCH 2/6] app/dumpcap: fix storing port identifier

[Ben Magistro <koncept1@gmail.com>]

When dumpcap adds an interface, the port was not being preserved. This
results in the structure being initialized and the port field being set
to 0 regardless of what port was actually selected. This unset field is
then used in both the enable and cleanup calls. This could result in the
capture occurring on the wrong interface.
