ANDROID: Incremental fs: fix u64 integer cast to pointer
Compiler (arm-linux-gnueabihf-gcc 8.3.0) complains about an invalid cast
of an __aligned_u64 integer to a pointer on 32-bit architectures. Using
u64_to_user_ptr() for the cast fixes the following warning:
fs/incfs/pseudo_files.c: In function ‘ioctl_create_file’:
fs/incfs/pseudo_files.c:656:10: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
656 | (u8 __user *)args.signature_info,
| ^
Bug: 183339614
Fixes: bc6a70e849cc (ANDROID: Incremental fs: Remove signature checks from kernel)
