[Xcb] [PATCH] util-cursor: Fix minor memleak and fix the RENDER version check

Hi,

attached are two patches for util-cursor. The first one handles a minor memory
leak and is quite trivial.

The second one is a little less trivial: CreateCursor was added to RENDER in
version 0.5 and CreateAnimCursor is new in version 0.8. However, util-cursor
only checked if the RENDER extension is present and then assumed that all
requests are available.

Cheers,
Uli

    but benchmarking how many GL pages you can print per second
    was deemed too silly to merge
