iOS: Ignore next touch event if keyboard has lost focus during touch

Browse Source 
If the iOS virtual keyboard as lost focus because it was slided down,
the next touch event on an inactive screen area will be mapped to the
keyboard. This kicks an assertion, because the keyboard is expected to
be visible. The case that the keyboard has been deactivated by sliding
it down is not covered.

This patch replaces the assertion by setting self.enabled to NO, which
reflects the keyboard deactivation.

Fixes: QTBUG-112246
Pick-to: 6.6 6.5 6.2
