Btrfs: fix wrong parse of extent map's tracepoint

The tracepoint of extent map doesn't parse @flag correctly, we set @flag via set_bit(), so we need to parse it on a bit bias. Also add the missing flag, EXTENT_FLAG_FS_MAPPING. Signed-off-by: Liu Bo <bo.li.liu@oracle.com> Signed-off-by: Chris Mason <clm@fb.com>
