Finish devices after their finish callback returns
The problem is that the finish callback might still have to work with the
device, so it can't be made unusable yet. This is in contrast to what
cairo_surface_finish() does, but when finishing a surface it's quite unlikely
that its cairo_surface_t still has to be passed around to functions outside of
the backend.
This "fixes" some problems with the xcb-surface-source test where
_cairo_surface_snapshot()-style snapshots break when the underlying
cairo_device_t is finished. (In the following backtrace, cairo_device_acquire
fails because the device's ->finished member is already TRUE)

ps: Update xlib-surface-source ref images
Since 9948b5180a, the *-surface-source tests draw a different image (a
translucent region was added). However, the ref images for xlib-surface-source
with cairo-ps weren't updated and thus the test failed.
