Subject: [PATCH] Fix the failure related to io_uring_prep_cancel (#10165)

Summary:
Fix for Internal jobs are failing with
```
 error: no matching function for call to 'io_uring_prep_cancel'
      io_uring_prep_cancel(sqe, posix_handle, 0);
      ^~~~~~~~~~~~~~~~~~~~
note: candidate function not viable: no known conversion from 'rocksdb::Posix_IOHandle *' to '__u64' (aka 'unsigned long long') for 2nd argument
static inline void io_uring_prep_cancel(struct io_uring_sqe *sqe,
```

User data is set using `io_uring_set_data` API so no need to pass posix_handle here.
