Unfortunately dynamic_cast can fail. When it does, it returns a null

pointer. So any pointer gotten from a dynamic_cast should be checked.
In mythmainwindow, the eventFilter member function does a
dynamic_cast of the event into a key event.
This patch makes sure we don't dereference that key event pointer if the
dynamic_cast didn't work.
