[patch] ocfs2: cleanup error handling in o2hb_alloc_hb_set()

[Dan Carpenter <dan.carpenter@oracle.com>]

If "ret" is NULL, then "hs" is also NULL, so there is no need to free
it.  config_group_init_type_name() can't fail if the name ("heartbeat"
in this case) is less than CONFIGFS_ITEM_NAME_LEN (20) characters long
so we can just remove this error handling code.
