Benjamin Marzinski 086cc672e1 GFS2: mark the journal idle to fix ro mounts 
When gfs2 was mounted read-only and then unmounted, it was writing a
header block to the journal in the syncing gfs2_log_flush() call from
kill_sb(). This is because the journal was not being marked as idle
until the first log header was written out, and on a read-only mount
there never was a log header written out. Since the journal was not
marked idle, gfs2_log_flush() was writing out a header lock to make
sure it was empty during the sync.  Not only did this cause IO to a
read-only filesystem, but the journalling isn't completely initialized
on read-only mounts, and so gfs2 was writing out the wrong sequence
number in the log header.

Now, the journal is marked idle on mount, and gfs2_log_flush() won't
write out anything until there starts being transactions to flush.
