xwayland: remove limits for wayland pointer

Browse source 
This change helps when an X11 window receives pointer
events into the part of the window that is out of screen bounds.

Example:
1. window is located at -50,-50 (root)
2. receives absolute pointer event at 10,10 (surface local),
3. it is then translated to -40,-40 (root coordinates)
4. then clamped to the screen geometry and becomes 0,0
5. 0,0 (root) is translated to window local: 50,50

This patch effectively removes those limits and the window
will get the Enter/Motion events at 10,10(local) and -40,-40(root)
as expected.
