Fix the core dump reported in https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9258 :

After calling wtap_close(), set the wth to NULL so we don't try to close it
again later. (The core only happens when tshark isn't keeping up with dumpcap's
file rotation.)

Wireshark still has a problem but it's a different one.
