reiser4_trim_fs() generate empty (atom->capture_count == 0) atoms which
still have non-empty delete sets. That is, such atoms take a "goto done"
shortcut in commit_current_atom().
First, this shortcut must not preclude calling current_atom_complete_writes()
to process and detach atom's flush queues (otherwise atom_isclean() will
return false).
Second, reiser4_post_write_back_hook() needs to be called explicitly
to process atom's delete sets.
