[win-pv-devel] [PATCH] Suppress warning 4715

[Owen Smith <owen.smith@xxxxxxxxxx>]

__CacheMaskScan can trigger a compiler warning with some compilers due
to not all return paths returning a value. The path that does not return
a value calls KeBugCheckEx, which would leave unreachable code. Disable
the specific warning for this function.
