winenas.drv: Avoid a warning in a trace on x86_64 [try 2]

[Alexandre Goujon]

This time, I tested the patch in a 32 and 64 build tree.
num_bytes is if type AuUint32 which is typedef'ed from CARD32 in audio/audio.h.
The following http://lists.x.org/archives/xorg-devel/2009-October/002399.html is worth reading.
