[Qemu-devel] [PULL 3/5] qxl: drop mono cursor support

[Gerd Hoffmann <kraxel@redhat.com>]

The chunk size sanity check in qxl_render_cursor works for
SPICE_CURSOR_TYPE_ALPHA cursors only.  So support for
SPICE_CURSOR_TYPE_MONO cursors must be broken for ages without anyone
noticing.  Most likely it simply isn't used any more by guest drivers.
Drop the dead code.
