cluster/afr: Enable eager-lock
Eager-lock is disabled by default.
Use cluster.eager-lock on/off to change the config.
write-behind on and eager-lock off is not supported configuration.
In afr, when eager-lock is enabled the inode lock on fd is taken
using the fd address as the lk-owner. So the lock is
interchangableale between the inode-locks on the same fd.
