Clean up indentation a bit.

Clean up indentation a bit.

In "capture_input_new_file()", don't call the callbacks unless we
succeed in opening the new file.  Have "capture_info_new_file()" return
a success/failure indication.

Improve the message logged when we fail to open the new file if we're
only opening it for the quick packet counts.  We really should put up an
alert box and give up on the capture at that point.
