[Qemu-devel] [PATCH v2 2/3] Remove screendump dummy functions.

[Gerd Hoffmann <kraxel@redhat.com>]

The code in console.c verifies whenever a screen_dump function
pointer is present before calling it, so there is no need to supply an
dummy function.  Remove them.  Also report an error to notify the user
that he didn't got a screenshot.
