pallet-mmr

  1. uses sp_io::offchain_index API to save full MMR leaves content to offchain db,
  2. it also defines an offchain_worker() fn that does canonicalization of data in offchain db.

Issue
When --enable-offchain-indexing=true is not set, (1) doesn't write anything to offchain db, while (2) keeps on spamming error logs on failures to do canonicalization.

Proposed solution
Also move (2) under the --enable-offchain-indexing=true flag so it only runs when actually useful.
