Wayland: mouse ungrab not working

In remote-viewer when pressing shift+12 the mous should be ungrabed, however its not working under wayland if SPICE_MOUSE_MODE_SERVER is used. The problem seems to be that remote-viewer fist ungrabs the keyboardtry_keyboard_ungrab and then the mouse try_mouse_ungrab. Due what i assume is an error in ungrab_pointer in spice-widget.c

if (d->mouse_mode == SPICE_MOUSE_MODE_SERVER) {
    spice_wayland_extensions_disable_relative_pointer(widget);
    spice_wayland_extensions_unlock_pointer(widget);
}

never gets called if the keyboard is already ungrabed.

I made a simple fix for that, by just moving it out of the if block: 3b78fbbee8c30e84de38f64776b0508f7919942f.patch
