Pull erofs fixes from Gao Xiang:
 "Two bugfixes to fix the 4KiB blockmap chunk format availability and a
  dangling pointer usage. There is also a trivial cleanup to clarify
  compacted_2b if compacted_4b_initial > totalidx.

  Summary:

   - fix the dangling pointer use in erofs_lookup tracepoint

   - fix unsupported chunk format check

   - zero out compacted_2b if compacted_4b_initial > totalidx"
