Meta server: fix chunk allocation restart logic with metaServer.appendPlacementIgnoreMasterSlave set to 1. The bug was resulting in intermittent chunk allocation failures with append, as the restart logic was making the first slot empty, assuming "master" selection. Fix typo in variable and parameter names.
Merge branch 'master' into topic/krb
