Check and repair index under the store metadata lock #27768

  1. Check index under the store metadata lock 

    Today when we get a metadata snapshot directly from a store directory,
we acquire a metadata lock, then acquire an IW lock. However, we create
a CheckIndex in IndexShard without acquiring the metadata lock first.
This causes a recovery failed because the IW lock can be still held by
`snapshotStoreMetadata`. This commit makes sure to create a CheckIndex
under the metadata lock.
