mark_dirty: Check surface status

Browse source 
This problem was introduced in commit "xlib: Implement SHM fallbacks and fast
upload paths". Before, cairo_surface_mark_dirty() directly called
cairo_surface_mark_dirty_rectangle() with special "magical arguments" and thus
didn't need any checks on the surface status.

Fixes: api-special-cases
