Nature: Red Hat Satellite should not lose data while provisioning.

Steps to reproduce:
1.) Enter Host Data
2.) Operating System page is OK, enter the password
3.) Do NOT enter MAC Address for the interface, press the "Submit" Button
4.) Error message: "Some of the interfaces are invalid. Please check the table below." (as expected)
5.) Enter MAC, press OK

(other steps as above)

Actual results:
