fs-verity: Avoid u64_to_user_ptr() clang warning

Browse source 
Clang emits -Wdefault-const-init-var-unsafe when using u64_to_user_ptr()
due to the typecheck() macro creating an uninitialized dummy variable.

Replace u64_to_user_ptr() with an explicit cast through uintptr_t to
avoid the warning while keeping the same behavior.
