io_uring: don't use int for ABI
commit cf73d9970ea4f8cace5d8f02d2565a2723003112 upstream.
__kernel_rwf_t is defined as int, the actual size of which is
implementation defined. It won't go well if some compiler / archs
ever defines it as i64, so replace it with __u32, hoping that
there is no one using i16 for it.
