ocfs2/dlm: Remove BUG_ON in dlm recovery when freeing locks of a dead node

During recovery, the dlm frees the locks for the dead node. If it finds a
lock in a resource for the dead node, it expects that node to also have a
ref in that lock resource. If not, it BUGs.

ossbz#1175 was filed with the above BUG. Now, while it is correct that we
should be expecting the ref, I see no reason why we have to BUG. After all,
we are freeing up the lock and clearing the ref.

This patch replaces the BUG_ON with a printk(). Hopefully, that will give
us more clues next time this happens.
