    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.
