Subject: [PATCH] client: Fix ref counting double free with hardlink

Peforming a hard link through the libcephfs interface causes
a double free on shutdown, due to the Client::link call decrementing
the parent (of the target) directory's inode.  This fix removes the
put_inode(dir) call, to match the behavior of Client::ll_link.
