server: send lookup on root inode when itable is created

This is a backport of http://review.gluster.org/#/c/13837

 * xlators like quota, marker, posix_acl can cause problems
   if inode-ctx are not created.
   sometime these xlarors may not get lookup on root inode
   with below cases
   1) client may not send lookup on root inode (like NSR leader)
   2) if the xlators on one of the bricks are not up,
      and client sending lookup during this time: brick
      can miss the lookup
   It is always better to make sure that there is one lookup
   on root. So send a first lookup when the inode table is created

 * When sending lookup on root, new inode is created, we need to
   use itable->root instead
