cluster/afr: handle sending NULL dentry name for inode link in self-heal-daemon

* Without the dentry name, dentry cannot be created in inode_link, which
 leads to trying to access the null dentry to check if it is cyclic and
 thus segfault. So send the parent inode also NULL, which just returns
 the proper inode after assigning the gfid and type to the inode without
 trying to create dentry.

* Handle failures such as dentry_create returning NULL, in inode_link
  properly and return NULL in such cases.

* Increase the lru limit of inode table of self-heal-daemon to 2048
