Subject: [PATCH 101/104] tier/dht: check for rebalance completion for EIO error

When an ongoing rebalance completion check task been
triggered by dht, there is a possibility of a race
between afr setting subvol as non-readable and dht updates
the cached subvol. In this window a write can fail with EIO.
