With commit 6eee29bf2a86eee890051b566db26628e2e52918 (InterfaceTreeList: Enable
all editable columns) if the Manage Interfaces dialog is used to hide any
interfaces, subsequent attempts to unhide ALL interfaces will silently fail.

In version 2.3.x the Qt InterfaceTreeList is currently undergoing a series of
changes.  The commit above appears to have introduced an regression where at
most one less than the actual number of interfaces can be un-hidden once any
interface has been configured as hidden.

This issue was replicated on both OS X and Linux.

Steps to reproduce:

1 - Open the Wireshark - Capture Interfaces dialog.

2 - Click on the [Manage Interfaces ...] button to open the Manage Interfaces
dialog.

3 - In the Manage Interfaces dialog configure one or more columns as hidden by
clearing one or more checkboxes under the Show column.

4 - Click on the [Ok] button.  The Manage Interfaces dialog will close.  Please
note that on OS X the Wireshark - Capture Interfaces will likely have moved
behind the Wireshark window perhaps because Wireshark's main window is
immediately updated to show the new list of interfaces.

5 - Bring the Wireshark - Capture Interfaces dialog back to the foreground.

6 - Note that the now hidden interfaces will no longer be displayed in the
Wireshark - Capture Interfaces dialog.  Be aware that the hidden interfaces MAY
still appear on the Main Wireshark window depending on the state of the new
Show Hidden Interfaces drop down list item.

7 - From the Wireshark - Manage Interfaces dialog open the Manage Interfaces
dialog a second time.

8 - In the Manage Interfaces dialog enable the Show checkbox for ALL
interfaces, we want NO hidden interfaces.

9 - Click [Ok] to close the Manage Interfaces dialog.

10 - Note that all of the previously hidden interfaces are still hidden.

11 - Open the Manage Interfaces for a third time.

12 - This time enable showing all but one interface (it does not matter which
particular interface is left hidden).

13 - Click [Ok] to close the Manage Interfaces dialog.

14 - The Wireshark - Capture Interfaces dialog will now list all but the one
still configured hidden interface.

Expected behavior:  After having hid one or more interfaces, one should be able
to un-hide all interfaces concurrently.
