[cairo] [PATCH 6/7] surface: Make parameter naming consistent between header and impl

[Bryce W. Harrington]

This fixes this set of distcheck errors generating docs:

  src/cairo-surface.c:1668: warning: Parameter described in source code
  comment block but does not exist. FUNCTION:
  cairo_surface_set_device_scale Parameter: sx.

  src/cairo-surface.c:1668: warning: Parameter described in source code
  comment block but does not exist. FUNCTION:
  cairo_surface_set_device_scale Parameter: sy.

  src/cairo-surface.c:1668: warning: Parameter description for
  cairo_surface_set_device_scale::x_scale is missing in source code
  comment block.

  src/cairo-surface.c:1668: warning: Parameter description for
  cairo_surface_set_device_scale::y_scale is missing in source code
  comment block.
