[GFS2] Update journal accounting code.
A small update to the journaling code to change the way that the "extra" blocks are accounted for in the journal. These are used at a rate of one per 503 metadata blocks or one per 251 journaled data blocks (or just one if the total number of journaled blocks in the transaction is smaller). Since we are using them at two different rates the old method of accounting for them no longer works and we count them up as required. Since the "per transaction" accounting can't handle this (there is no fixed number of header blocks per transaction) we have to account for it in the general journal code. We now require that each transaction reserves more blocks than it actually needs to take account of the possible extra blocks. Also a final fix to dir.c to ensure that all ref counts are handled correctly. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
