Peter Hutterer 23394c7fea Xi: ungrab device when releasing a passive grab without ButtonReleaseMask (#71878) ...

If an touch triggers an async button grab and that grab does not have the
ButtonReleaseMask set, the TouchEnd is never delivered, deliveries is 0  and
the grab is never deactivated.

If the grab is pointer async and keyboard sync, the keyboard events are stuck
in EnqueueEvent until some other pointer event terminates the grab.

Change this to check for the number of listeners. If we're about to deliver a
TouchEnd to a passive pointer grab, the number of listeners is already 1 -
pointer grabs always accept so other listeners were removed.
