Identical throughout dri2, dri3 and drisw. Next patch will add more
common code, so rather than duplicating it factor out the function.
Note: this also sets eglError on failure. Something that's quite
inconsistent throughout the codebase.
v2: Call xcb_disconnect() on error (Eric)
Note: use xcb_disconnect() even in the xcb_connection_has_error() case
as per the manual:
... memory will not be freed until xcb_disconnect...
