Subject: [PATCH] md-cluster: don't update recovery_offset for faulty device
Git-commit: 0ea9924abe125a0c1277484f1a3d512b3f45c320
Patch-mainline: v4.17-rc2
References: bsc#1093023
Device could become faulty when clustered array handling
METADATA_UPDATED msg, so we don't need to call read_rdev
for this device.
