GFS2: Fix gfs2_replay_incr_blk for multiple journal sizes
Before this patch, if you used gfs2_jadd to add new journals of a size smaller than the existing journals, replaying those new journals would withdraw. That's because function gfs2_replay_incr_blk was using the number of journal blocks (jd_block) from the superblock's journal pointer. In other words, "My journal's max size" rather than "the journal we're replaying's size." This patch changes the function to use the size of the pertinent journal rather than always using the journal we happen to be using. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
