Fix mobile data toggle status not correct

When toggle off the switch and dismiss the confirmation dialog.

This issue is caused by dialog's on dismiss listener not set, only
confirm and cancel listener is set.

Since confirm and cancel will also called dismiss listener, set a
dismiss listener cannot fix this issue.
So when need display confirmation dialog, change the toggle status back
to on, and set to off when confirmed to fix this issue.
