cluster/afr: Don't lookup/forget inodes
Problem:
All inodes that are looked-up are always forgotten without fail in
afr removing the benefits of them being in lru. This same code can
cause crashes if between inode_lookup, inode_forget in afr if the
top xlator does inode_forget(0).
Fix:
Don't use lookup/forget in afr. No benefits are there at the moment
for keeping this code. It is impossible to prevent top xlators to
do inode_forget(0). Found similar instances in ec
and removed them even though those code paths are not going to
be executed in any place other than heal-daemon.
