XKB: Fix sense inversion for core MapNotify events
Due to an unfortunate sense inversion incident while switching from a
if (foo) { ... } to if (!foo) continue; style in f06a9d, we punished any
client who attempted to use XKB to restrict the MapNotify events they
wanted by sending them exactly the events they _didn't_ want, and
nothing else.
NewKeyboardNotifies (coming from a client setting the map with an XKB
request, when switching between master devices, etc) weren't affected,
but this would impact anyone using xmodmap-style core requests. Could
explain a fair bit.
Clarified the comments while I was at it.
