st/nine: fix stack corruption due to ABI mismatch
This fixes various crashes and hangs when using nine's 'thread_submit'
feature.
On 64bit, the thread function's data argument would just be NULL.
On 32bit, the data argument would be garbage depending on the compiler
flags (in my case -march>=core2).
Fixes: f3fa7e3068512d ("st/nine: Use WINE thread for threadpool")
