[PATCH 12/12] vhost-vdpa: add explicit cast for void* to u64__user*

From: xiongweimin <[email protected]>

Add explicit cast from void __user* to u64 __user* for maximum
compatibility with static analysis tools. While the implicit conversion
is valid C, explicit casts improve sparse checking compatibility.
