This patch is just a cleanup. Function gfs2_get_block() just calls function gfs2_block_map reversing the last two parameters. By reversing the parameters, gfs2_block_map() may be called directly and function gfs2_get_block may be eliminated altogether. Since this function is done for every block operation, this streamlines the code and makes it a little bit more efficient.
