If we have no pointer focus and weston_compositor_pick_view() returns NULL
default_grab_pointer_focus() will test the unset sx, sy output parameters
from weston_compositor_pick_view().
Instead, assume that since both pointers are NULL focus hasn't changed and
we don't need to update pointer focus.

This fixes an error reported by valgrind. I think the patch is correct but
it does stop pointer->focus_signal from being emitted when focus switches
from NULL to NULL. I think that shouldn't have happened anyway?
Initializing sx, sy to wl_fixed_from_int(0) would silence the warning too,
but I think this way is more correct...
