fix a crash in the GTK "Interface Management" dialogue

for Pipes and Local Interfaces
(Capture / Options / Manage Interfaces)

if you start with an empty dialogue, select a pipe using Browse and
press Save, wireshark crashes because of a strcmp() against the
uninitialized pipe_name

initialize pipe_name to NULL and make sure its value is reset when the
dialogue is closed

don't add a pipe unless there's an active selection in the pipe list
(which may be "New Pipe")
