Change prototypes for __chk_user_ptr and __chk_io_ptr
to take const void* instead of void*, so that code can pass
const void* to them. (Right now sparse does not warn
about passing const void* to void* functions, but that
is a separate bug that I believe Josh is working on,
and once sparse does check this, the changed prototypes
will be necessary.)
