ocfs2: use regular seq_show_option for osb_cluster_stack
While cleaning up seq_show_option_n()'s use of strncpy, it was noticed that the osb_cluster_stack member is always NUL-terminated, so there is no need to use the special seq_show_option_n() routine. Replace it with the standard seq_show_option() routine.
