Subject: [PATCH v2 1/3] ocfs2: Remove some useless functions

__ocfs2_node_map_set_bit() and __ocfs2_node_map_clear_bit() are just
wrapper around set_bit() and clear_bit().

The leading __ also makes think that these functions are non-atomic just
like __set_bit() and __clear_bit().

So, just remove these wrappers and call set_bit() and clear_bit()
directly.
