[PATCH weston 3/4] data-device: Lookup drag resources using the focussed surface

[Rob Bradford]

From: Rob Bradford <rob at linux.intel.com>

Rather than relying on focussed resource to get the client to lookup the
drag resource with instead derive the client from the focussed surface.

This is equivalent as the focussed resource is derived from the focussed
surface in the weston_keyboard_set_focus function.
