Description of problem:

While adding an iSCSI device, if you forget to select any of the discovered iSCSI devices (or uncheck all of them), you can still click the "Login" button.  After that, you are unable to login to any iSCSI devices.

Version-Release number of selected component (if applicable):
 * anaconda-15.29-1

How reproducible:
 * pretty easy, and happens every time when entering incorrect data.

Steps to Reproduce:
1. Follow steps outlined at https://fedoraproject.org/wiki/QA:Testcase_Anaconda_ISCSI_No_Authentication
2. After iSCSI discovery finds available volumes, unselect all volumes and click 'Login'
  
Actual results:

THe user is able to click 'Login' and the dialog closes.  From that point, any attempts to re-add an iSCSI device fail.

Expected results:

The 'Login' button should be deactivated (unclickable) if no devices are selected.

Additional info:

* Nominating for a F15 nice-to-have fix since I suspect this won't be a disruptive change.
* See attached log files ...
