arch/tile: fix futex sanitization definition/prototype mismatch
Commit 8d7718aa082aaf30a0b4989e1f04858952f941bc changed "int" to "u32" in the prototypes but not the definition. I missed this when I saw the patch go by on LKML. We cast "u32 *" to "int *" since we are tying into the underlying atomics framework, and atomic_t uses int as its value type.
