GFS2: Eliminate unused "new" parameter to gfs2_meta_indirect_buffer
It turns out that the "new" parameter to function gfs2_meta_indirect_buffer was always being passed in as zero. Therefore, this patch eliminates it and simplifies the function. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
