Subject: [PATCH] Switch reqlsns[0].request_lsn to arrow operator in
 neon_read_at_lsnv() (#10620) (#10687)

## Problem

Currently the following line below uses array subscript notation which
is confusing since `reqlsns` is not an array but just a pointer to a
struct.

```
XLogWaitForReplayOf(reqlsns[0].request_lsn);
```

## Summary of changes

Switch from array subscript notation to arrow operator to improve
readability of code.

Close #10620.
