dm thin: reinstate missing mempool_free in cell_release_singleton

Fix a significant memory leak inadvertently introduced during
simplification of cell_release_singleton() in commit
6ed4382707820f5078cf55801f25710879ef35ce ("dm thin: fix stacked bi_next
usage").

A cell's hlist_del() must be accompanied by a mempool_free().
Use __cell_release() to do this, like before.
