cluster/afr: Refactor inodelk to handle multiple domains
- afr_local_copy should not be memduping locked nodes, that would mean that lock is taken in self-heal on those nodes even before it actually takes the lock. So removed memdup code. Even entry lock related copying (lockee info) is also not necessary for self-heal functionality, so removing that as well. Since it is not local_copy anymore changed its name. - My editor changed tabs to spaces.
