[PATCH v2] XArray: minor documentation improvements

[Tamir Duberstein]

- Replace "they" with "you" where "you" is used in the preceding
  sentence fragment.
- Use "erasing" rather than "storing `NULL`" when describing multi-index
  entries. Split this into a separate sentence.
- Add "call" parentheses on "xa_store" for consistency and
  linkification.
